    Abstract: The present disclosure relates to a method for preparation of a high temperature-resistant bismuth yellow pigment. The method comprises: mixing an oxide which served as a matrix and dopan with a bismuth source, a vanadium source, or a molybdenum source, and then placing the mixture into a mill for grinding to obtain a precursor; further calcining and crushing the precursor to obtain the high temperature-resistant bismuth yellow pigment powder. The bismuth yellow pigment has a bright color, a b* value greater than 90, a stable performance, and a high heat-resistance above 800° C. The method is environmentally friendly without waste, and reaction conditions are simple. Doping of BiVO4 crystal lattices by incorporation of oxides can be achieved, so that the particle size and distribution of the bismuth yellow pigment can be effectively controlled while the color performance of the bismuth yellow pigment is greatly improved.
