SETT ATT TILLVERKA EN FORMKROPP AV KERAMIK

摘要

A method for the manufacturing of a molded member from a ceramic material, including compressing the molded member within an evacuated capsule of a high temperature-resistant glass under a pressure acting thereabout until the molded member attains a non-porous condition. The working materials for the glass capsule are applied to the molded member in a non-vitrified state; and the coated member is subjected to the reaction temperature of the materials under a vacuum until there is formed a cohesive glass layer enveloping the molded member which will constitute the capsule.
