Purity quartz glass is mainly depends on the raw material, the raw material with high purity silicon tetrachloride production of quartz glass purity can reach six nine (99.9999%); with purified natural quartz production of high-quality quartz glass purity can reach four nine, used in the semiconductor industry; with high-quality production of ordinary quartz natural quartz glass purity of about three nine.
