High Borosilicate Glass (also known as hard glass) is based on the conductive characteristics of glass at high temperature. Internal heating to achieve glass melting, processed by advanced production technology, because the linear thermal expansion coefficient is (3.3 0.1)× 10-6/K, it is also called "borosilicate glass 3.3". It is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. Because of its excellent performance, it is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light source, craft jewelry and other industries.
