A Study on the Formation and Sintering of Powders Synthesized from ZrO 2 Micro- and Nanoparticles from Fluoride Solutions

The effect of the conditions of synthesis on the formation of micro- and nanoparticles of zirconium dioxide from a fluoride solution has been studied. It is shown that the finest particles are formed by precipitation from dilute solutions with a zirconium concentration of 0.02–0.04 mol/L and impurities of polyvinyl alcohol at a mass ratio of m Zr : m PVC 1 : 0.1. To sinter ZrO 2 nanoparticles, it is proposed to use the electroconsolidation method in a vacuum to obtain ceramics with high values of the hardness and elastic modulus.
