Abstract

PURPOSE:To improve the precision workability and releasability of a glass molded body by using a molding tool obtd. by forming a silicon layer on a base and a surface layer, etc., on the silicon layer. CONSTITUTION:This molding tool for a glass molded body is obtd. by forming a silicon layer on a base and a surface layer or an intermediate layer and the surface layer on the silicon layer. The base is made of tungsten carbide, silicon carbide, silicon nitride or cermet and has superior heat resistance, thermal shock resistance and strength at high temp.
