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.
