Types, uses and processes of quartz glass

        Quartz glass is made by melting all kinds of pure natural quartz (such as crystal, quartz sand, etc.). The coefficient of linear expansion is very small, which is 1 / 10 ~ 1 / 20 of that of ordinary glass. It has good thermal shock resistance. Its heat resistance is very high. Its regular use temperature is 1100 ℃ ~ 1200 ℃, and its short-term use temperature can reach 1400 ℃. Equipment for refining high purity glass and special quartz products. Because it has high spectral transmission and will not be damaged by radiation (other glasses will darken after being irradiated by radiation), it is also an ideal glass for spacecraft, wind tunnel window and spectrophotometer optical system.

        Quartz glass is a kind of special industrial technology glass with single component of silica. The glass has high hardness up to Mohs 7, high temperature resistance, low expansion coefficient, good heat shock resistance, chemical stability and electrical insulation, and can pass through ultraviolet and infrared rays. Except hydrofluoric acid and hot phosphoric acid, it has good acid resistance to general acids. According to transparency, it can be divided into two categories: transparent and opaque. According to the purity, it can be divided into three categories: high purity, ordinary and doped. It is made of crystal, silica and silicide by high temperature melting or chemical vapor deposition. Melting methods include electric melting method, gas refining method, etc. [more]
