Using potassium carbonate, ammonium phosphate, zirconium dioxide, and cobalt oxide as raw materials, a kind of potassium zirconium phosphate ceramic pigments with bright purple color at high temperature were obtained through a series of optimizing experiments.
The raw materials are weighed accurately according to every single composition, and then ball milled and sintered at 1400 o C for 1 h.
This kind of solid solution is mostly formed in solid inorganic materials.
