Preparation method for modified fused zirconia and praseodymium yellow pigment
The invention relates to a preparation method for modified fused zirconia and praseodymium yellow pigment. The method includes: firstly conducting grinding and homogenization treatment to control the grain composition of fused zirconia in a reasonable scope, improving the specific surface area of fused zirconia, and then adding an appropriate active adhesive to conduct mixing so as to improve the reaction activity of fused zirconia, thus obtaining modified fused zirconia with specific surface area and reaction activity both close to chemical zirconium. The ceramic pigment produced from the modified fused zirconia has temperature resistance close to that of high temperature resistant ceramic pigment prepared from chemical zirconium. The modified fused zirconia can completely replace chemical zirconium to produce high temperature resistant ceramic pigment, the application bottleneck of fused zirconia in the high-end ceramic pigment field can be overcome, and the production cost of high temperature resistant ceramic pigments is reduced.
