Conclusions It was established that in the range 1900–2100°C in vacuum damage occurs to the chemical composition of the yttrium oxide with respect to the content of oxygen, accompanied by the formation of anionic vacancies, centers of coloring, and change in the phase composition of the specimens. In the range 2200–2300°C there occurs intense volatilization of the specimens of yttrium oxide, and moreover this is preceded by the phase inversions C→B→A, and the A modification, impoverished of oxygen, is volatilized.
