Conclusions
The sintering of pure yttrium oxide was studied in the range 1800–2100°C with a soak of up to 30 h. The kinetics of densification and grain growth were studied during sintering, and the corresponding activation energy levels were calculated.
The influence of additional high-temperature processing on the change in properties and structure of Y2O3 ceramics was studied. It is shown that yttrium oxide ceramics (relative density about 97% of the theoretical) after processing in vacuum for a period of 10–100 h at 1900–2100°C possess a stable density and dimensions, slight grain growth, and loss in weight.
