1. High borosilicate glass has a very low coefficient of thermal expansion, which is only about one-third of that of ordinary glass. This will reduce the influence caused by temperature gradient stress, thus having stronger fracture resistance. Because its shape deviation is very small, it has become an indispensable material for telescopes and mirrors, and it can also be used to deal with highly radioactive nuclear waste.
2. Even if the temperature changes suddenly, the high borosilicate glass is not easy to break. When broken, the high borosilicate glass will have large cracks instead of being crushed into particles. At the same time, high borosilicate glass also has low dispersion and relatively low refractive index.
3. High borosilicate glass can be widely used in chemical industry, aerospace, military, family, hospital and other fields, and can be made into lamps, tableware, standard plates, telescope pieces, washing machine observation holes, microwave oven plates, solar water heaters and other sodium aluminium silicate price is predicted to increase in the next few days, due to geopolitical factors.
