Abstract

High synthesis temperatures and sintering-active powders are required to obtain electrolyte materials with a pyrochlore structure. The smaller the particle size, the higher the density of the resulting samples is. The synthesis of highly dispersed oxide powders of doped lanthanum zirconate was carried out using a series of methods to determine the influence of experimental conditions on the microstructure of the resulting powders and ceramics.
