The knowledge of borosilicate glass

- Apr 02, 2018-

The coefficient of linear expansion of G3.3 borosilicate glass is 3.3±0.1x10-6/K, based on sodium oxide (Na 2 O), boron oxide (B 2 O 3), and silicon dioxide (SIO 2). A glass of ingredients. The borosilicate content of this glass composition is relatively high, namely boron: 12.5 ~ 13.5%, silicon: 78 ~ 80%, so this kind of glass is called high borosilicate glass belongs to borosilicate glass PYREX glass acid resistance. Alkali water resistance, superior corrosion resistance, good thermal stability, chemical stability and electrical properties, it has chemical resistance, thermal shock resistance, good mechanical properties, withstand high temperature and other characteristics.
