Homogeneous precipitation preparation method of nanoscale yttrium-doped zirconium oxide powder

The invention relates to a homogeneous precipitation preparation method of nanoscale zirconium oxide powder. The preparation method comprises the following steps: dissolving ZrOCl2. 8H2O and Y2O3 in a container A with water to obtain a solution A; dissolving urea in a container B with water to obtain a solution B; mixing the solution A and the solution B in a container C, and mechanically stirring by heating to obtain a precipitate; adjusting the pH value of the precipitation solution by using an alkaline reagent to obtain a precursor solution C; aging the precursor solution C, centrifugally washing, drying and grinding to obtain a precursor; and calcining the precursor to obtain the nanoscale zirconium oxide powder. The method is low in cost, simple to operate, mild in reaction condition and easy to control, and the prepared nano zirconium oxide powder has the advantages of being good in dispersity, narrow in particle size distribution, uniform in particle size and the like. 本发明涉及一种纳米级氧化锆粉体的均相沉淀制备方法。本发明的制备方法
