Linear expansion coefficient G3.3 borosilicate glass is 3.3 persons 0.1 × 10-6 / K, based on sodium oxide (Na2O), boron oxide (B2O3), silicon dioxide (SIO2) as a basic ingredient of glass. The borosilicate glass composition higher content of boron, respectively: 12.5 to 13.5%, Si: 78 to 80%, so that this type of glass is borosilicate glass. Belonging borosilicate glass PYREX glass. Acid and alkali water, excellent corrosion resistance, has good thermal stability, chemical stability and electrical properties, it has a chemical resistance, thermal shock resistance, good mechanical properties, withstand high temperature and other characteristics.Borosilicate glass 3.3 is one of transparent colorless glass, through wavelength is between 300 nm to 2500 nm, transmissivity is more than 90%. Coefficient of thermal expansion is 3.3. It can acid proof and alkali , the high temperature resistant is about 450°C. If course handling , the high temperature resistant can reach 550°C or so. Apply to lighting fixture , chemical industry , electron, high temperature equipment and so on.
