Influence of hydrolysis method on the sol-gel formation of the yttria-alumina system with use of alcoholates

Abstract

The influence exerted by hydrolysis methods and introduction of a hydrolyzing agent into the systems formed by the alkoxide technology, which uses yttrium salts and alumium secondary butylate as the initial components, was determined. It was found that the hydrolysis stage affects the conditions of the subsequent thermal treatment, the phase formation in the system, and the granulometric composition of the prepared powders. The most favorable conditions for formation of yttrium aluminum garnet are achieved upon excess water hydrolysis in the presence of an aqueous solution of yttrium salt.
