Colorless Quartz Optical Glass is an optical material with excellent transparency, high temperature ...
Borosilicate glass is made by using the characteristics of conducting electricity of glass under high temperature and by heating the glass inside to realize the melting of glass. Borosilicate glass a colorless transparent glass with a very low coefficient of thermal expansion and resistance to high temperature and 200 degree temperature fluctuations. The transmittance ≥ 90% and the coefficient of thermal expansion 3.3 were obtained with the transmission wavelength between 300nm and 2500nm. Acid and alkali resistance, high temperature resistance of about 400℃, such as through special treatment can reach about 550℃. Borosilicate glass is one of the best heat-resistant instrument glass, widely used in all kinds of heat-resistant glass instruments, such as chemical anti-corrosion equipment and pipe fittings, laboratory glass instruments, is also a good lamp workers instrument glass.
