    Abstract: PROBLEM TO BE SOLVED: To inexpensively provide molten quartz glass suitably usable for various kinds of optical material utilizing ultraviolet light, visible light and infrared light, a member for manufacturing a semiconductor, a member for manufacturing a liquid crystal and a member for manufacturing a micro electro mechanical system (MEMS). SOLUTION: The molten quartz glass contains ≤5 ppm OH group, 12.0 Pa s coefficient of viscosity at 1215°C and expresses 1×10 -10 cm 2 /sec or less diffusion coefficient of Cu ion at 20-100 μm depth from the surface in the thermal diffusion of Cu ion in the atmosphere. The molten quartz glass is obtained by forming raw material silica powder into cristobalite and melting in a non-reducing atmosphere. COPYRIGHT: (C)2010,JPO&INPIT
