Internal heating to achieve glass melting, processed by advanced production processes, due to the coefficient of thermal expansion of the line (3.3 ± 0.1) × 10-6 / K, also known as "borosilicate glass 3.3". It is a low expansion rate, high temperature resistance, high Special glass materials with high strength, high hardness, high light transmittance and high chemical stability are widely used due to their excellent properties. It is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light source, craft jewelry and other industries.
