01-Product Name:
Borosilicate glass also called high borosilicate glass.Both high borosilicate glass and quartz glass are high temperature resistant glass ,which can be different shape and size to meet your requirement.
02-Product Preview:
The linear expansion coefficient of G3.3 high borosilicate glass is 3.3 ± 0.1 × 10-6 / K. It is a glass based on sodium oxide (Na2O), boron oxide (B2O3), and silicon dioxide (SIO2). The glass composition has a high content of borosilicate, which is boron: 12.5 ~ 13.5% and silicon: 78 ~ 80%, so this kind of glass is called high borosilicate glass. It belongs to glass in borosilicate glass. Acid, alkali and water resistance, excellent corrosion resistance, good thermal stability, chemical stability and electrical properties, so it has chemical resistance, thermal shock resistance, good mechanical properties, high temperature and other characteristics.
03-Difference between quartz glass and high borosilicate glass:
1. The composition is different: the high borosilicate glass composition is sodium oxide, boron oxide, silicon dioxide, among which the borosilicate content is higher: 12.5 ~ 13.5%, silicon: 78 ~ 80%; quartz glass composition is silicon dioxide: content is 99.99
2. Different temperature resistance: the high boron silicon temperature is at the strain temperature of 520ºC, and the softening temperature is 820ºC;
Quartz glass has a temperature of 1100ºC and a melting point of about 1700ºC
3. Quartz glass is not only resistant to high temperature, but also acid, corrosion and electrical insulation.
