- Q:Quartz products are mainly used in photovoltaic and semiconductor industry which links, please expert pointing!
- The photovoltaic industry with loaded fixture quartz wafer, the amount is large, our students also have automatic quartz boat loading machine.
- Q: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.
- Q:Can porcelain crucible, quartz crucible and alumina crucible be filled with aluminium hydroxide?
- Today, the world semiconductor industry in developed countries has used this crucible instead of transparent quartz crucible is small. He has high purity and strong heat resistance, large size high precision, good heat insulation, energy saving, stable quality and other advantages.
- Q:Is the quartz crucible drawn by monocrystalline silicon disposable?
- The used quartz crucibles have been contaminated. Therefore, quartz crucibles used for single crystal drawing are disposable
- Q:A brief introduction to quartz crucibles
- The quartz crucible is suitable for melting samples with K2S2O7, KHSO4 as flux, and using Na2S207 (first drying at 212 degrees) to treat samples with flux.
- Q:What happens when carbon carbon crucibles are cracked?
- If the whole crucible is used, the external force of the crucible will cause the fiber damage of the carbon crucible when the quartz crucible is taken.In addition, the carbon carbon crucible may cause cracks during the fabrication of the preform.
- Q:At present, the quartz crucible used in Czochralski silicon is used to make use of barium coating, but how does the oxygen content rise when the coating react with the silicon melt?
- Oxygen reduction process can be resolved by other processes, oxygen control within 0.8E17 process, the current strong monocrystalline silicon enterprises, has been very easyIn addition, a message can be disclosed that there are large enterprises in the development of new coatings, because barium coating process is foreign patent, the Chinese people are in Tort
- Q: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.
- Q:How much fire resistance is quartz crucible?
- The quartz glass crucible is usually used for the production of monocrystalline silicon, and the production temperature of single crystal is 1450 degrees
- Q:Why are fused quartz transparent and opaque?
- Quartz glass is a kind of special glass containing only single silica component. Because of the type of technology, raw materials, quartz glass, glass, often called foreign silicate quartz glass, fused silica, fused quartz, synthetic fused silica, and no clear concept of transparent, translucent, opaque quartz.
