DEVICE FOR MANUFACTURING QUARTZ GLASS

摘要

PROBLEM TO BE SOLVED: To provide a device for manufacturing quartz glass which can prevent generation of static electricity in raw material silica powder and further can supply the raw material silica powder without contamination of impurities. SOLUTION: In the device for manufacturing quartz glass containing a raw material tank, a raw material transportation part, a burner and a fusion furnace, at least a wall part which comes into contact with the raw material silica powder is formed of a sintered compact consisting of silicon carbide or silicon carbide and silicon and the wall part which comes into contact with the raw material silica powder is grounded.
