The influencing factors of ceramic pigment color effect

For ceramic pigment, its color effect depends on the existence of coloring ions status first, secondly depends on the pigment production process conditions, and the latter affects the former.
1. The coloring ion valence and the coordination number
Coloring ions in the outer electrons of different valence structure will be different, when light energy level splitting and electron transition is not the case; Coloring ions coordination number is different, the formation of the ligand state is different, there are differences between the spectral absorption band wavelength position, thus present a different color. The color of ceramic pigment material mainly is the transition metal ions and compounds of rare earth metal ions. Transition metal ions and the color of rare earth metal ions were related to 3 d, 4 f electronic transition layer.

2 the making craft of ceramic pigments
The making craft of ceramic stains is also the important factors that affect the color. If the same kind of pigment, different process conditions, the Ceramic Color  difference is very big also.

(1) the selection of raw materials. ceramic raw materials mainly affecting the effects of pigment color coloring materials and mineralizer. Different forms of coloring materials as well as the introduction of different kinds of mineralizer, will make the same quality of material presents a different color effect.
When making chrome-tin red material, for example, respectively with Cr2O3, K2Cr2O7, BaCrO4 introduced three different forms of chromium compound such as the same number of shading element Cr, it was found that chemical pure Cr2O3 is the best form of the introduction of Cr. Cr2O3 ingredients directly after the calcine not only material layer and uniform color, and the color is the most lively, with less purple tones; K2Cr2O7 as the source of the Cr made of pigment not only the color purple is heavier, and the fluctuation of raw material layer and the color is also very inconsistent; While BaCrO4 unfit to make color deeper chrome-tin red material, the introduction of the three kinds of chromium compounds, it is the color of the light and uncertain, made with brown pigment hue.
Again, such as, in the making craft of zirconium TieGongSe material, with ferric oxide is introduced into Fe2O3, deep coral red pigment, With ferrous sulfate introduction of Fe2O3, coral red pigment is bright. At the same time, to make the color selection of mineralizer, fluoride is the main factors influencing the pigment synthesis, its main effect is to strengthen of pigment synthesis coloring ions embedded in zircon lattice, and the intensity of the role, directly affect the synthetic pigment color effect.

(2) the processing of raw materials. The processing of raw materials mainly include two aspects, one is single the fineness of raw material, the second is the mixing degree of the batch. In general, a single material fineness of the thinner, the better synthetic pigment color; After batch mixed more evenly, the synthetic pigment color is pure, even. There is, however, exceptions, for example, somebody was making use of plasma decomposition synthesis of zircon zirconium vanadium blue material experiment is found that plasma decomposition zircon (PDZ) the fineness of the thinner, the synthesis of zirconium vanadium blue material is the more shallow light color, the reason is that the fineness of the thinner PDZ, the greater its reactivity, the vanadium colorants has not been able to enter the ZrSiO4 is generated ZrSiO4 crystal lattice temperature, thus make into the lattice of V4 + greatly reduced, resulting in synthesis of pigment color shallow light.

(3) the color pigments synthesis conditions. Ceramic pigment synthesis products generally are high temperature, thus the synthesis conditions are the key factors that influence the color. Different kinds of Pr.Yellow pigment and the use of different materials of the same color material, its synthetic conditions (and atmosphere calcine temperature, synthetic time) are different, should take a test to determine its synthetic conditions.

(4) composite processing. Composite after fine grinding, washing, to become a Ceramic Colors product. In general, composite processing fineness of the thinner, the cleaner the washing, the ink color is pure, deep. Zirconium TieGongSe after synthetic material, for example, there are usually some Fe2O3 not into the ZrSiO4 lattice, such as not using acid pickling to remove this part of Fe2O3, pigment when use, will not get the pure coral red tones, and because of Fe2O3 exists in glaze, and produce other glaze defects.

Ceramic Glaze Colour Stain

Ceramic Color Pigment is a type of introduction of grey colour, colour makeup coloring material in the soil, glaze and other ceramic decoration supplies, also recognized as colorant. Numerous synthetic pigment is generally colored inorganic compounds, occasionally also can use hair colour metal oxide pigment or supplies colored mineral raw circumstances do.
1.1 the classification of the pigment(ceramic stains color pigments)

1.1.1 classification according to the various of use According to the utilizing circumstances higher, the ceramic pigment can be divided into: colour temperature and low temperature higher, coloring material, glaze coloring material.
Pigment: (1) utilizing temperature and cryogenic temperature pigment below temperature generally 850 ℃, utilized Higher in ceramic glaze decoration. utilized temperature pigment can use temperature degrees in 1000 ~ 1300 ℃, the temperature can be numerous in the preparation of colour ceramic glaze Higher. correct temperature pigment can match with utilized flux and substitute pigment whilst at low temperature (700 ~ 850 ℃, utilized the low temperature pigment higher be utilized to substitute higher temperature pigment two in higher temperature.
utilizing grey colour material: belong to much less temperature usually pigment, varieties, demands dosage. Grey hair coloring material powerful colour higher, hair cost stability, to adapt to the temperature is three, the higher is utilizing.
(developing) glaze coloring material, also belong to six temperature fundamental pigment. Will the class in the following in the production of sanitary ceramics, pigment by 1 ~ required% plus quantity added to the Ceramic Colors glaze, therefore the temperature attain for firing, can get the objective glaze, colour generally the every of decoration. Note: grey simple and glaze coloring material seem much more be replaced by two other, otherwise, colour to Developing presently other glaze defects.
1.1.consist of classified by primary colour sanitary ceramics production and so on Every the use of pigment in the colour couple of: red, pink, yellow, green, blue, purple, brown, gray, black, sorts. colour of these complete and have a impact sensible of colour, and impact application three, to make easy use of kind type of ceramic pigment.
1.1.Kind classification according to the ore phase composition and structure
(1) couple of compound easy pigment: this generally of pigment refers to the coloring of transition element oxide, chloride, carbonate, nitrate and hydroxyl. Some chromate (e.g., lead chromate red), uranium salts (such as uranium acid sodium red), antimony (e.g., & yellow) with sulfur acid salt (such as cadmium sulphide yellow), selenide (such as cadmium selenide red) and attribution and so on. higher pigment with a decreasing overall performance compounds, consequently is not type temperature resistant, and generally atmosphere resistance and chemical stability utilized is also poor, situation, this utilized of pigment only once more following in low temperature higher, or utilized to higher circumstances two temperature synthetic pigment strong in answer temperature kind.
easy single oxide mixture searching generally pigment: an additional type higher for material of coloring oxides or its corresponding salts can type with steady strong of resistance to answer temperature oxide compound to even though a strong answer sorts, type this strong answer is composed of two kind of oxides, but with X - ray appraisal, only show is a kind of oxide lattice, so named single oxide kind kind strong pigment. Belong to this class of pigment of chromium corundum answer manganese peach, corundum kinds aluminum chrome red, rutile common titanium tin lilac and chrome yellow, baddeleyite vanadium zirconium yellow and so on. A single oxide higher various three of pigment in kind is type temperature resistant, but for the atmosphere of the adaptability and stability of the erosion of glaze melt is mainly.
(common) composite oxide amongst pigment: this 3 of pigment two spinel, in addition to pyrochlore and perovskite. Spinel pigment chemical two formula for AB2O4 or AO ` B2O3, five them A divalent metal ions, B for 4 medium metal ions,
Such as CoO, Al2O3, When A and B are not 1:two, according to incomplete spinel, such as CoO, exact same.kind Al2O3
When B for various valence metal ions of divalent metal ions, constitute A class (like) spinel, such as kinds zno, TiO2.
The type variety of spinel or strong answer of spinel can known as chromatography a wide two of two kind, constitute the so-two composite spinel,
Like (CoO, Mn) o. (Cr, Fe) higher o3 in black ink, ZnO (Al, Fe) two, o3 is brown, (Co, zinc) o. Al2O3 is blue, (Ca, zinc) o. Cr2O3 green. Belongs to the spinel type of pigment are: red, zinc chrome aluminum zinc titanium yellow (higher zno, TiO2) with little temperature and peacock blue [(Co, zinc) o. (Cr, Al) great o3], and so on. This attributes of pigment with type temperature resistant, impact sensitivity to atmosphere and chemical stability, great kind, is a answer of ceramic pigment use strong is answer.
When coloring oxides with perovskite (CaO, TiO2) or calcium strong tin (CaO ` SnO2) matrix answer of perovskite pigment is formed when,
Such as Cr kind kind formed in calcium tin CaO ` SnO2 perovskite chrome-tin red
V colour a number of formed in perovskite, CaO TiO2, vanadium titanium yellow. Perovskite colour and colour of hair components depends on the matrix mineral pigment coloring oxide species, listed in table 1 various hair common of two three in four matrix. Pyrochlore mineral chemical three formula for A2B2X7, A is 1, four, five, strong valence metal ions, B for answer, four, kind valence metal ions, X for O, OH, and F. Burn the green stone material with antimony lead acid (Pb2Sb2O7) type sorts in the Fe and Al, are all yellow.
(types) silicate 1 pigment: this type of pigment composed of two strong of answer, strong answer is coloring oxide and silicate minerals matrix kind three formation of three Typical The other is a coloring oxide involved in formation of silicate compound. The former red such as cobalt magnesium olivine, the latter kind zhe garnet chrome green (kind cao, Cr2O3, kind sio2).
growing silicate three pigment are zhe garnet, sphene and zircon, willemite three and olivine primarily of ink varieties are also two. Zhe garnet mineral chemical formula is primarily R2 + o. R23 + O3 ` and so on sio2, the R2 + kind Ca2 +, magnesium capability +, Mn2 +, Fe2 +, R3 + higher for Al3 +, Fe3 +, Cr3, +, instance. This colour of pigment structure tightly, appropriate of kind temperature. Victoria green, for strong, the mineral calcium for chromium zhe garnet, pure green, answer stability, is strong for the lead zinc glaze, glaze, lime glaze, and is not sensitive to the atmosphere. Magnesium olivine answer, such as cobalt red, it is Co2 + replace the two amongst of magnesium magnesium olivine (substitutional six eight), its formula is: four (Co, Mg) o. SiO2 or (Co, Mg) o. SiO4, two them: the CoO MgO style: SiO2 = (.very best ~ .strong) : (1.answer ~ 1.kind) : 1 (mole ratio). The chemical formula which colour characterizes the sphene to CaO, TiO2, SiO2 (titanium sphene). When titanium is tin replacement for tin sphene CaO, SnO2, SiO2. When colored metal ions and sphene sorts Kind of sphene pigment. Sphene mainly pigment hair strong depends on the however of coloring oxide and sphene.
discover zircon pigment answer typical coloring ions into ZrSiO4 lattice, has kind to An additional out the colour way. There is component had been ceramic colours Turquoise Blue zircon pigment zirconium vanadium blue, Pr.Yellow  zirconium praseodymium yellow, red iron oxide. enhance zircon pigment is a package, namely the capability technique is surrounded by a ZrSiO4 lattice, such as CdS and Cd (Se) S essential ZrSiO4 package, can path its improvement to use temperature and glaze melt erosion resistant. This higher is an created abroad with cordierite, silicon zinc, barium calcium feldspar, feldspar, diopside and apatite lattice for maternal pigment.

Match to ITACA's Ceramic Black Colors.

Black ceramic pigments in the finalceramic glaze colors not only by the nature of the ink itself and the influence of the basic glaze, is a product the influence of sintering temperature and sintering atmosphere. Modern glass and crystal field theory suggests that the glaze of black paint the coloring ions in general are closed, the spinel lattice oxygen ions formed various coordination state. So the pigment color balance is affected by the two aspects: oxygen ion electric fields and cationic molecular motion of the basic glaze.

Can be seen in the experiment, all the factors affecting the stability of pigment color (such as chemical composition, sintering temperature and amount of pigment is introduced into) is by adjusting the role of oxygen ions and the cation of coloring and the balance of the whole formula to new color. And from the point of view of thermodynamics and the analysis of crystal field theory, Co, Cr, Mn, Fe after calcining synthetic spinel AB2O4 type mixed crystal, various coloring ions could occupy A, B, in the low energy tetrahedron and octahedron ligand field in the crystal lattice. Relatively, Fe and Mn ions in the lattice is in unstable condition, there exists a Fe 3 +, Fe2 +, Mn 2 + 3 + Mn and dynamic balance, the electronic easy coloring ions, shifting between ligand, produced by oxidation - reduction reaction, destroy paint color balance. Black material with mixed spinel crystal structure, generally by the Fe2O3 - Cr2O3 - MnO2 - Co2O3 synthesis. Co2O3 is the indispensable component in black material, otherwise, the black material is not pure black. But Co2O3 is expensive, the black material cost is high.

In recent years, many manufacturers are racing to develop cobalt free black material in order to reduce the cost, but it seems the effect is not obvious, the black material is used for containing cobalt and black. Because the Fe2O3 content is higher in black material, when added to the glaze, some incomplete synthesis of spinel structure of Fe2O3 will enter glaze, this requires basic glaze glaze for good liquidity, high temperature and low viscosity, otherwise, make the glaze blister easily. Basic glaze of ZnO, MgO style can cause a relatively dirty black glaze color to move, therefore, request as far as possible in the basic glaze excluding ZnO, oxide of MgO style; Black material is suitable for barium calcium glaze, glaze, lead glaze and high temperature liquid feldspar glaze, more color in boron lead fritted glaze, in zircon opacified glaze is not pure black glaze. With the development of the black ceramic pigment, from the original spinel structure to develop package type black pigment, from the original solid consistency method production gradually turned to the SHS method or microwave synthesis method, from the shuttle kiln, tunnel kiln with sagger with synthetic development in direct synthesis of rotary kiln, from the use of chemical raw materials to use natural mineral and all kinds of industrial slag raw material, can be seen, with the development of science and technology and people's demand on black material, more color purity, low cost, low pollution, low energy consumption of the black ceramic pigment will be popularized and applied.- body stain Ceramic Colors ceramic tile color six star pigments.
