High Temperature Resistant High Purity Quartz Rod Light Guide Rod Quartz Glass Tube Custom Quartz Instrument
Product Description
Quartz glass features:
1. High purity :99.99%-99.999% SiO2.
2. Hardness: Mohs hardness 5.3-6.5.
3. High temperature resistance: continuous work below 1200℃,
4. Acid and alkali resistance: except hydrofluoric acid, quartz glass does not react with any acid and alkali. Stability is 30
5. Twice as much as ceramic and 150 times as much as stainless steel
6. Electrical insulation: 10000 times of ordinary glass.
7. High transmittance: 85-95%, depending on the spectrum.
8. Excellent thermal shock stability: low thermal expansion coefficient, 5.5×10-7/℃.
