Abstract

A finely crystalline powder of the tetragonal solid solution based on zirconia with a crystal size of less than 40 nm is synthesized from zirconium and cerium peroxides. The amorphous phase formed as an intermediate product upon decomposition of the peroxides is characterized by structural disordering and involves chemical defects (OH-, H2O). Crystallization of (Zr1 - x Ce x )O2 solid solutions (x = 0–0.2) and the sequence of phase and structural transformations of precursors upon heating are investigated. It is found that, during heat treatment at temperatures in the range 500–1200°C, recrystallization and growth of grains occur very slowly (from 5 to 60 nm). This makes it possible to obtain nanomaterials for different applications.
