FAQ
- What's the difference between a quartz crucible and a porcelain crucible?
- The quartz crucible and the ceramic crucible have different temperature resistance, and the acid and alkali are different
- External surface macular problem of arc type quartz crucible
- After cleaning the pot can not see the macula, and heated to about three, Baidu appeared macular, because the reason is simple: no cleaning.
- Is the quartz crucible drawn by monocrystalline silicon disposable?
- Yes, once a quartz crucible has been used, it will crack or break even after high temperature and cooling. And the single crystal drawing requires a high-purity quartz crucible.
- Can porcelain crucible, quartz crucible and alumina crucible be filled with aluminium hydroxide?
- Quartz glass crucible can be used below 1450 degrees. It is divided into two kinds: transparent and opaque
- What are the main differences between the corundum crucible and the quartz crucible?
- Quartz crucible can be used below 1650 degrees. It is divided into two kinds: transparent and opaque. The translucent quartz crucible fabricated by arc method is a basic material for developing large scale integrated circuits. It has the advantages of high purity, strong heat resistance, large size, high precision, good heat insulation, energy saving, stable quality and so on;
- Quartz products are mainly used in photovoltaic and semiconductor industry which links, please expert pointing!
- Quartz can be used in many industriesYou should say that the PV and semi industry should be polycrystalline silicon or monocrystalline siliconThe manufacture of quartz products is first made into quartz powder, which can be used as quartz glass tubes, quartz plates, crucibles and so onThe crucible is very demanding, because it's Gao ChunshaThe crucible is stable because of the physical properties of the quartz material and can be used to refine polycrystalline silicon - monocrystalline siliconThe industry itself has recently come into contact, and it should be said that the prospects for development are good
- Can the quartz crucible react with calcium oxide or calcium hydroxide at high temperature?
- Quartz crucibles should be noted for use:(1) HF can not contact, can not be used for heating, carbonate and oxide caustic alkali and alkaline earth metal.(2) the quartz is fragile and easy to break, so we should pay attention to it.(3) except HF, the ordinary dilute inorganic acid of quartz glass crucible can be used as cleaning liquid.4. Heating calcium oxide or calcium hydroxide at high temperature, usually using iron crucible.
- What are the sizes of arc quartz crucibles?
- HF can not contact, high temperature, easy and caustic alkali carbonate reaction and alkali metal. 3. quartz crucibles are suitable for melting samples with K2S2O7, KHSO4 as flux, and using Na2S207 (first drying at 212 degrees) to treat samples with flux.
