Abstract

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.
