Physical Properties:
| 1. Purity | SiO2 content is more than 99.99% |
| 2. Temperature | Softening point temperature is about 1730 degrees Celsius ,1100 degrees Celsius in a long time used ,short-time maximum use temperature is up to 1450 degrees Celsius |
| 3. Anti-corrosion | Quartz glass is acidic materials, except hydrofluoric acid and 300 degrees Celsius thermal phosphoric acid, on any other acids were shown to be inert, is the best anti acid materials. At room temperature, alkali and salt on quartz glass corrosion degree is minimal |
| 4. Transmittance good performance | Compare to ordinary silicate glass, transparent quartz glass in the whole wavelength head excellent permeability. In the infrared spectrum through than ordinary glass; in the visible region, quartz glass transmittance is relatively high ,above 85%-90%. In the UV spectral region especially in the ultraviolet region, the spectral transmission is much better than other glass,about 80% |
| 5. Good electrical insulation properties | Quartz glass with high dielectric strength and very low electrical conductivity, even in high temperature, high pressure and high frequency,it can still maintain high dielectric strength and resistance, in the application of the band almost no dielectric loss, therefore the quartz glass is an excellent high temperature dielectric insulating material |
| 6.Thermal stability | The thermal expansion coefficient of quartz galss is extremely small ,it can be able to adapt drastic temperature changes |
