Alumino-Silicate Glass

Alumino-silicate glass is mainly composed of Si-Ca-Al-Mg and other alkali metal oxides through a scientific ratio combination, in which the content of K2O+Na2O ≤0.3%, belongs to the non-alkali aluminum silicate glass system, after high temperature tempering treatment with high temperature resistance, high pressure resistance, acid and alkali resistance and other excellent physical and chemical properties, is a variety of high pressure glass window excellent material.It is mainly used in power plant, petrochemical, nuclear power plant, deep-sea exploration equipment and other kinds of high temperature and high pressure steam package on the high pressure water level gauge glass window.
