Quartz window usually smelted and cut by quartz, they have a silica content of over 99.99%. The hardness is seven grades of Mohs, and it has the characteristics of high temperature resistance, low thermal expansion coefficient, thermal shock resistance and good electrical insulation performance.
Advantage of Quartz Glass Plate/Sheet:
1. High purity , SiO2> 99.99%.
2. High temperature resistant.
3. Good thermal stability.
4. Acid-proof, Alkali-proof.
5. Excellent electrical insulator.
6. High transmittance.
