What kind of raw material is glass made of?
Composition of common glass chemical oxides (Na2O, CaO, 6SiO2)Glass is usually divided into oxide, glass, and non oxide glass by major components. Non oxide glass varieties and a small number, mainly sulfur glass and halide glass. Chalcogenide glass anion for sulfur, selenium and tellurium, can stop short wave light by yellow, red, and near infrared light, which has low resistance, switching and memory characteristics. Having low refractive index, low dispersion, and often used as optical glass.
