First, the chemical composition determines the high temperature resistance. For example, SiO2, B2O3, A12O3, ZrO2, ZnO and MgO can increase the high temperature resistance of glass, reduce the coefficient of thermal expansion of glass, and improve the thermal stability of glass.
Secondly, it is related to the processing technology. Different heat-resistant glasses have different processing methods. After different processing treatments such as heat treatment, annealing and quenching, the temperature and other mechanical properties that the glass can bear will be improved accordingly.
Moreover, it is related to processing technology and equipment. The same raw materials, after exquisite processing technology, advanced equipment processing out of the glass high temperature performance is far higher.
Finally, the use process also affects the performance of high-temperature glass. If the glass operates in a critical state for a long time or often appears extremely cold and hot, it will affect the heat-resistant performance of the glass.
