Introduction to quartz glass
A single component glass of silica. This glass has a hardness of up to seven grades of Mohs, with high temperature resistance, low expansion coefficient, thermal shock resistance, chemical stability and electrical insulation, and can transmit ultraviolet and infrared rays. In addition to hydrofluoric acid and hot phosphoric acid, it has good acid resistance to common acids. Divided into two categories: transparent and opaque. According to the purity, it is divided into three categories: high purity, common and doped. It is made of crystal, silica and silicide as raw materials, which are melted at high temperature or chemical vapor deposited. The melting method includes an electrofusion method, a gas refining method, and the like.
