top quality quartz boat manufacturer
quartz boat/glass solar boat/wafer glass
Â
Â
Material Properties:
Â
1.Quartz has the good properties of heat resistance, ozone resistance, air aging resistance.
2.The surface of quartz is smooth , it’s hard to adhere to theanimalcule, there’s little affinity with the depositÂ
   sediment.
3. Quartz has the properties of
resistance , grease resistance ,
chemical resistance.
Â
Specifications  :
Â
Semiconductor and electronics industry with semi-cutaway quartz boat Enhanced support can be welded
Â
 1. Purity: SiO2 content is more than *9.*9%, transparent quartz boat  can reaches above *9.*9%
Â
2.Temperature : softening point temperature is about ***0 degrees Celsius ,***0 degrees
   Celsius in a long time used ,short-time maximum use temperature is up to ***0 degrees Celsius ;
Â
3. Anti-corrosion : Quartz glass is acidic materials, except hydrofluoric acid and **0 degrees CelsiusÂ
   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.
Â
4. Transmittance good performance :Â Compare to ordinary silicate glass, transparent quartz boat
   for oxidation,wafer diffusion, in the whole wavelength head excellent permeability. In the infrared
   spectrum through than ordinary glass; in the visible region, quartz glass transmittance is relatively Â
   high ,above *9%**2%. In the UV spectral region especially in the ultraviolet region, the spectralÂ
   transmission is much better than other glass,about *0%.
Â
5. Good electrical insulation properties :Â 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, thereforeÂ
    the quartz glass is an excellent high temperature dielectric insulating material.
Â
6.Thermal stability :The thermal expansion coefficient of quartz boat for oxidation,wafer diffusion, is
   extremely small ,it can be able to adapt drastic temperature changes ;
Â
We can make products according to the requirements of our customers.
