An experiment on precipitation of zirconia by urea, urotropin, and ammonium hydroxide precipitants is described. The morphological and phase composition of the precipitated powders are investigated. It is shown that a buffer has a positive effect on reducing the agglomeration. The agglomeration factor for the ammonium hydroxide precipitant is reduced from 175 to 40. A powder consisting of “soft” agglomerates having a developed surface and easily disintegrated in milling to a size of < 1 µm is obtained. Individual particles are 0.06–0.08 µm in size.
