Is borosilicate glass fragile
High borosilicate glass is less fragile than ordinary glass, but it is also fragile because of its properties. When broken, borosilicate glass cracks tend to be larger rather than crushed (it will unit rather than split).
High borosilicate glass (also known as hard glass) is made of the conductive property of glass at high temperature, through heating inside the glass to achieve glass melting, and 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 transmittance and high chemical stability. Because of its excellent performance, it is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light source, process jewelry and other industries.
