More Information
Summary:The invention provides a process for simply and easily producing high-purity flame-processable synthetic opaque quartz glass including large-sized one; and synthetic opaque quartz glass. The invention relates to a process for the production of synthetic opaque quartz glass which comprises the step of heating and firing a porous quartz glass under a pressure of 0.15 to 1000 Mpa at a temperature of 1200 to 2000 DEG C. The porous quartz glass is one prepared by accumulating quartz glass fine particles formed by the hydrolysis of a silicon compound with oxyhydrogen flame.
