Abstract

A new method for preparing gels as a precursor for SiO2-MxOy (M=Al, Ti, Zr) glasses of an arbitrary composition was investigated. The gels were formed via polymetalloxanes from hydrolytic condensation of metal chelates of ethyl acetoacetate or condensation polymerization of the chelate with silicic acid. The method permitted to prepare transparent gel plates of MxOy and binary SiO2-MxOy component systems.
