Due to the very low coefficient of thermal expansion. This will reduce the impack caused by temperature gradient stress and thus have stronger fracture resistance. Even if the temperature suddenly changes, it is not easily broken.
In addition, borosilicate glass has good fire resistance and high physical strength. Its mechanical properties, thermal stability, water resistance, alkali resistance, acid resistance, and other properties are greatly improved. So it can be widely used in various fields such as chemical industry, oil and gas industry, home appliances, lighting, microwave ovens, instrumentation, etc.
