Conclusions
The degree of translucence of Y2O3 ceramics depends on the amount of additive, the grinding time of the components, and the calcination temperature of the powder. The influence of the technological factors is interrelated; upon them depends the fineness of the powder, the uniformity of the distribution of the additive, and the degree of synthesis of the solid solution.
It was established that a poreless high-translucence ceramic can be produced with 6–10 mole % added HfO2 or ZrO2. An x-ray phase analysis was used to determine the lattice constant of the solid solution in the Y2O3-HfO2 and Y2O3-ZrO2 systems and the x-ray density of Y2O3 ceramics containing up to 20 mole % added HfO2 or ZrO2.
