Problems solved by technology

[0004] After research, it is found that the reason why the ceramic pigments produced by fused zirconia such as praseodymium yellow material has poor temperature resistance is that the specific surface area of ​​fused zirconia powder is small and the reactivity is small, resulting in the inability of coloring elements in the process of pigment synthesis. Completely filled into the crystal lattice, the coloring power of the ceramic pigment will be weakened, and it will be easy to fade when used at high temperature, and the temperature resistance will be deteriorated

preparation example Construction

[0017] Specifically, please refer to figure 1 As shown, the preparation method of the modified fused zirconia in the embodiment of the present invention includes:

[0018] Grinding the fused zirconia particles into zirconia powder with a particle size of 3-5 μm and then homogenizing;

[0019] The lithium-sodium mixture and the magnesium-calcium mixture are mixed according to the weight ratio of 7:4, followed by high-temperature melting, water quenching treatment, water washing to neutrality, drying, and grinding to obtain an active adhesive with a particle diameter of 1-1.5 μm. The high-temperature melting temperature is 1300°C;

[0020] Mix the zirconia powder and the active binder, the amount of the active binder is 0.05wt% of the total amount of the mixture, and treat it at 200°C and 2MPa for 10h, so that the zirconia powder and the active binder are completely bonded. Together, they increase the reactivity of fused zirconia to obtain modified fused zirconia.

Abstract

The invention relates to a preparation method for praseodymium yellow pigment. The preparation method comprises the following steps: controlling the grain composition of fused zirconia in a reasonable range through grinding and homogenizing so as to improve the specific surface area of the fused zirconia; and then adding an appropriate active binder and allowing the binder and the fused zirconia to be fixedly bonded so as to improve reaction activity of the fused zirconia. Thus, modified fused zirconia with a specific surface area and reaction activity close to those of chemical zirconium is obtained. Ceramic pigment produced from the high-temperature-resistant modified fused zirconia has temperature tolerance close to that of high-temperature-resistant ceramic pigment prepared from chemical zirconium. The modified fused zirconia can totally replace chemical zirconium for production of high-temperature-resistant ceramic pigment; so bottlenecks in bottleneck of the fused zirconia in the fields of high-class ceramic pigment are overcome, and production cost for the high-temperature-resistant ceramic pigment is reduced.

Description

[0001] This case is a divisional application based on the invention patent with the application date of 2014-12-05, the application number 201410738251.X, and the name "a method for preparing modified fused zirconia and praseodymium yellow material" as the parent case . technical field [0002] The invention relates to the technical field of inorganic materials, in particular to a preparation method of praseodymium yellow material. Background technique [0003] my country is a big country in the production of ceramics. Zirconium-based pigments occupy an important position in the commonly used pigments for glazes and blanks of ceramics, such as zirconium-based three primary color pigments zirconium vanadium blue (Zr, V)SiO 4 , Zirconium Praseodymium Yellow (Zr, Pr) SiO 4 , Zirconium iron red (Zr, Fe) SiO 4 Therefore, the quality of fused zirconia, especially the high-temperature stability of the pigment, directly affects the quality of the produced zirconium vanadium blue a...
