1. Quartz crucible can be used below 1650 degrees, both transparent and opaque. The translucent quartz crucible made by the arc method is a large-diameter single crystal silicon, which is an indispensable basic material for the development of large-scale integrated circuits. Today, the world's semiconductor industry developed countries have used this to replace small transparent quartz crucibles. It has the advantages of high purity, high temperature resistance, large size, high precision, good heat preservation, energy saving and stable quality.
2, can not be in contact with HF, high temperature, it is easy to react with caustic and alkali metal carbonate.
3. The quartz crucible is suitable for melting the sample with K2S2O7, KHSO4 as a flux and treating the sample with Na2S207 (first dried at 212 degrees) as a flux.
4. Quartz is brittle and easy to break. Pay attention when using it.
5. In addition to HF, a common dilute mineral acid can be used as a cleaning liquid.
