PRODUCTION OF CRYSTALLIZED GLASS

摘要

PURPOSE:To produce crystallized glass by easy molding even in the case of a complex shape with high productivity without deteriorating characteristics such as mechanical strength. CONSTITUTION:An SiO2-CaO-MgO or SiO2-P2O5-CaO-MgO type crystalline powdery glassy material is kneaded with an org. solvent such as methanol and a binder such as polyvinyl butyral to prepare a slip. This slip is cast with a casting mold having hygroscopic property such as a gypsum mold and the resulting casting is released from the mold, dried and sintered to obtain the objective crystallized glass having a desired shape.
