Abstract

The variating of the physico-chemical properties of fine-grained powder based on ZrO2 in the ZrO2—Y2O3—CeO2—Al2O3—СоО system, produced by the combined method of hydrothermal synthesis / mechanical mixing with heat treatment in the range from 400 to1300 °C was investigated. It was found that the formation of CoAl2O4 was accompanied by a reversible phase transformation of T-ZrO2 → M-ZrO2. The powder is characterized by high activity to sintering. The research results will be used for microstructural designing of blue composites based on ZrO2.
