Quartz glass is a single-component glass of silicon dioxide, which is usually divided into two categories: transparent quartz glass and opaque quartz glass (fused silica). Transparent quartz glass has only a small amount of air bubbles, and has a very high optical uniformity and transparency. It is made of silicon tetrafluoride in a crystal box and melted at high temperature. The SIO2 content is above 99.95%, and the high-purity quartz glass content is 99.999%. . Opaque quartz glass is used vein quartz, quartz sand as raw material, and it is melted at high temperature. It contains more than 99.5% SIO2.
