High borosilicate glass is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high transmittance and high chemical stability. Because of its excellent performance, it is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light source, process jewelry and other industries. Its good performance has been widely recognized by all sectors of the world, especially in the field of solar energy, which has been widely promoted in Germany, the United States and other developed countries. Borosilicate glass is made by adding sodium silicate sand, soda water and ground lime to the glaze made of boron traditional glass

difference between high borosilicate glass and ordinary glass

1. Characteristics of high borosilicate glass

borosilicate glass has a very low coefficient of thermal expansion, about one third of ordinary glass. This will reduce the influence caused by temperature gradient stress, so it has stronger fracture resistance. Because its shape deviation is very small, it has become an indispensable material in telescopes and reflectors. It can also be used to treat high-level radioactive nuclear waste

borosilicate glass begins to soften about 821 ℃ (1510 ℉). At this temperature, 7740 type high viscosity borosilicate is 107.6 weight

2. Borosilicate glass is less dense than ordinary glass

although more and more resistant to thermal shock than other types of glass, borosilicate glass can still be broken due to rapid or uneven temperature changes. When broken, borosilicate glass cracks tend to be larger than crushed (it will be unit, not split)

optically, borosilicate glass has low dispersion (about 65 Abbe crown glasses) and relatively low refractive index (the whole visible light range is 1.51-1.54)

g3.3 the linear expansion coefficient of high borosilicate glass is 3.3 ± 0.1× 10-6/K is a kind of glass with sodium oxide (Na2O), boron oxide (b2o2) and silicon dioxide (SiO2) as basic components. The content of boron and silicon in this glass is high, which are boron: 12.5~13.5%, silicon: 78~80%, so this kind of glass is called high boron and silicon glass. It belongs to Pyrex glass in borosilicate glass. Acid, alkali and water resistance, excellent corrosion resistance, good thermal stability, chemical stability and electrical performance, so it has the characteristics of chemical corrosion resistance, thermal shock resistance, good mechanical performance, high temperature resistance, etc

the above is an introduction to the differences between high borosilicate glass and ordinary glass. I hope it will be helpful to you. For more information about glass, please continue to follow the information
