Title:
MANUFACTURE OF MONOLITHIC GLASS MEMBER
Document Type and Number:
Japanese Patent JPS60151232
Kind Code:
A
Abstract:
1. A method of manufacturing monolithic glass members by preparing a monolithic gel from an alcoholic solution comprising an alkoxy silane, in which the monolithic gel is dried by heating it in a hermetically closed container to a temperature above the critical temperature of the solvent and then reducing the pressure, after which the monolithic gel is heated to increase its density, characterized in that a gas is introduced into the hermetically closed container until a pre-pressure is attained which is so high that during the heating to a temperature above the critical temperature no boiling phenomena occur in the solvent.
