Abstract
Data on sintering of Y2O3 ceramics are presented. It is shown that the degree of sample sintering depends on the powder agglomeration, which is determined by the nature of the starting material and the conditions of Y2O3 production. Y2O3 powder produced from yttrium carbonate exhibits the best sintering characteristics. The samples thus obtained are sintered to a relative density of about 95% even at 1600°C. Dry treatment of various Y2O3 powders in a planetary mill equalizes their properties and reduces the sintering temperature substantially. Data on the properties of Y2O3 ceramics are presented.
