Quartz sight glass

News Detail

Quartz sight glass is a single component glass of silica. This glass has a hardness of up to seven Mohs, has high temperature resistance, low coefficient, thermal shock resistance, chemical and electrical insulation properties, and can transmit ultraviolet and infrared rays. In addition to heat, acid resistance to general acids. Divided into two categories according to degree. According to the purity, it is divided into three categories: high purity, ordinary and doped. Crystal, silica and silicide are used as raw materials, which are formed by high temperature melting or chemical vapor deposition. There are electric melting method and gas refining method.
