Preparation method of black yttrium-stabilized zirconium oxide powder

The invention belongs to the technical field of inorganic new materials, and particularly relates to a preparation method of black yttrium-stabilized zirconium oxide powder. The preparation method comprises the steps: mixing a zirconium oxychloride solution and a yttrium trichloride solution in a proportion; adding an organic acid to generate a gel, adding an ammonia water solution to neutralize and precipitate, washing, filtering and dechlorinating, calcining an obtained filter cake to obtain a precursor powder, adding a coloring agent and a binding agent, ball-milling, sanding and crushing,adding an adhesive and a release agent, uniformly mixing, spraying, granulating and drying to obtain the yttrium-stabilized zirconium oxide powder. The invention relates to the preparation method of black yttrium-stabilized zirconium oxide powder. The process is simple, the yield is high, the produced powder is good in stability, uniform in particle size distribution, good in flowability and stable in shrinkage rate; the
