| Purity quartz glass depends mainly on raw materials, high-purity silicon tetrachloride raw material 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. |
Analysis of quartz glass table lists the levels of impurities.
Will provide the actual analysis of the data the same batch of product when the product is shipped.
