Borosilicate glass - Wikipedia

Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (~3 × 10 −6 K −1 at 20 °C), making them resistant to thermal shock, more so than any other common glass.Such glass is less subject to thermal stress and is commonly used for the construction of ...
