Quartz crucible has the advantages of high purity, high temperature resistance, high dimensional accuracy, good heat preservation, energy saving, stable quality, etc., and its application is more and more extensive. The inspection of quartz crucibles is a very important part, and the detection of quartz crucibles is developing towards the field inspection direction!
We have excellent technology development capabilities, the high purity fused quartz crucibles for the solar grade mono-crystalline silicon application. We can also produce special types according to client’s technical drawing.
Advantage of Quartz crucible for melting:
1. High purity,Sio2>99.99%
2. Resistance high temperature and corrosion
3. Used for industry,laboratory

Quartz Crucible for Industrial
Quartz Crucible for Industrial
| 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 |
