Material Properties for Borosilicate Glass

High borosilicate glass (also known as hard glass), is characterized by the use of glass to conduct electricity at high temperatures. The glass is melted by heating inside the glass and processed by advanced production processes. The coefficient of thermal expansion is (3.3 ± 0.1). × 10^-6 / K, also known as "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. Due to its excellent performance, it is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light source. , craft jewelry and other industries.
