1. SiO2> 99.99% ,high purity quartz tube
2.Operating Temperature: 1250℃
SoftenTemperature: 1730℃
3.Excellent visual and chemical performance .
4. without surface coating and infectant.
5. Health care and environmental protection.
6. Any dimension can be made.
7.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.
8.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%.
9.Good electrical insulation properties:
Quartz boat 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.
