IELD: technological processes.
SUBSTANCE: use: to create optically transparent ceramics. Essence of the invention consists in the fact that the method for producing optically transparent ceramics based on lutetium oxide consists in sintering the calcined press powder in a spark plasma, the maximum permissible load used is applied before heating.
EFFECT: providing the possibility of reducing the extinction coefficient of ceramics based on lutetium oxide sintered in a spark plasma, more than 2 times.
