It is melting made of various kinds of pure natural quartz (such as crystal, quartz sand...etc). The linear expansion coefficient is very small, which is 1/10~1/20 of ordinary glass.It has good thermal shock resistance. Its heat resistance is very high, the frequent use temperature is 1100℃~ 1200℃, and the short-term use temperature can reach 1400℃.Quartz glass is mainly used in laboratory equipment and refining equipment for special high-purity products.
Quartz glass is an amorphous material with a single component of silica, and its microstructure is a simple network composed of tetrahedral structural units of silica.Because Si-O chemical bond energy is very large, the structure is very tight, so quartz glass has unique properties, especially the optical properties of transparent quartz glass are very excellent, Excellent transmittance in the continuous wavelength range from ultraviolet to infrared radiation, it is ideal glass for use in spacecraft, wind tunnel Windows, and spectrophotometer optical systems.
