Quartz substrates by Vritra Technologies

Customized Quartz plate/disc


Quartz glass consists of silica (SiO2) in amorphous form. It differs from traditional glass in which additives are added to lower the melting point. Due to high purity, Quartz plates have higher melting point. Quartz also offer superior optical properties than ordinary glass like ultraviolet transmittance. Due to these properties, it find applications in semiconductor and optical device fabrication. Also due to its high melting point and low thermal expansion it is used for making crucibles for high temperature furnaces .
