Characteristics Of High Borosilicate Glass

High borosilicate glass has a very low thermal expansion coefficient, only about one-third that of ordinary glass, which will reduce the impact caused by temperature gradient stress and thus has stronger fracture resistance. Even if the temperature changes suddenly, high borosilicate glass Not easily broken either. The shape deviation is very small, and when broken, borosilicate glass will show large cracks instead of shattering into particles. At the same time, high borosilicate glass also has low dispersion and relatively low refractive index.
