REFRACTORY MATERIAL FOR SMELTING OXYNITRIDE GLASS, METHOD FOR SMELTING OXYNITRIDE GLASS AND OXYNITRIDE GLASS OBTAINED BY THIS METHOD

摘要

PROBLEM TO BE SOLVED: To provide oxynitride glass which is transparent and colorless and has high strength and high rigidity by finding out a refractory material which is not cracked in spite of use for a long time at a high temperature as a container, etc., in manufacturing the oxynitride glass by a melting method. SOLUTION: The refractory material for smelting the oxynitride glass consists of a molybdenum-silicon-base metallic material essentially containing an intermetallic compound of molybdenum and silicon.
