Quartz crucible has many advantages such as high purity, high temperature resistance, large size and high precision, good heat preservation, energy conservation, and stable quality. It is becoming more and more widely used. The detection of quartz crucible is a very important step, and it is developing towards on-site detection.
1.Quartz crucible can be used under 1450ºC, which is divided into transparent and opaque. The semi-transparent quartz crucible made by electric arc method is an essential basic material for drawing large diameter single crystal silicon and developing large scale integrated circuits. Nowadays, the developed countries in the world's semiconductor industry have replaced small transparent quartz crucibles with this one. It has the advantages of high purity, strong temperature resistance, large size precision, good heat preservation, energy conservation and stable quality.
2.Do not touch HF. At high temperatures, it is easy to react with caustic soda and alkali metal carbonate.
3.Quartz crucible is suitable for melting samples with K2S2O7, KHSO4 as fluxes and treating samples with Na2S207 (firstly dried at 212ºC) as fluxes.
4.Quartz is brittle and easy to break, so attention should be paid when using it.
