Abstract

Abstract A method of consolidating fine pores of a porous glass by impregnating the fine pores with an energy decomposable compound exemplified by SiH 4 . Energy is applied to the decomposable compound thereby forming active species which bond with each other and the functional groups on the surface of the fine pores three-dimensionally to thus form a glass network structure in the pores.
