- Q:Can the quartz crucible react with calcium oxide or calcium hydroxide at high temperature?
- Silica is acidic oxide, with acidic oxides and alkaline oxides, transparency, alkali reaction,The reaction principle is: SiO2+CaO=CaSiO3SiO2+Ca (OH) 2=CaSiO3+H2OTherefore, the crucible will corrode and the medicine in the crucible will spoil.
- Q:What crucible is used to melt solid caustic soda?Why not quartz crucibles?
- Iron. React with ceramic or glass silica ash
- 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:A brief introduction to quartz crucibles
- Quartz crucible can be used below 1450 degrees. It is divided into two kinds: transparent and opaque. The translucent quartz crucible fabricated by arc method is the basic material for drawing large diameter monocrystalline silicon and developing large-scale integrated circuits. Today, the world's semiconductor industry developed countries have replaced the small transparent quartz crucible with this crucible. He has high purity and strong heat resistance, large size high precision, good heat insulation, energy saving, stable quality etc..
- 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: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;
- Q:What's the difference between a quartz crucible and a porcelain crucible?
- The quartz crucible is white and transparent, and the opal crucible is used below 1200 degrees. The transparent crucible is used below 1400 degrees. The ceramic crucible is used at 1400-1600 degreesThe quartz crucible is resistant to acid and alkali, but hydrofluoric acid is not availableCeramic crucible does not resist strong alkali
- Q:What are the sizes of arc quartz crucibles?
- 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. Today, the world's semiconductor industry developed countries have replaced the small transparent quartz crucible with this crucible. It has the advantages of high purity, strong heat resistance, large size, high precision, good heat insulation, energy saving, stable quality and so on.
- Q:Why are fused quartz transparent and opaque?
- China referred to as quartz glass, press process, use and appearance to the classification, such as transparent fused quartz glass, fused quartz glass, quartz glass, synthetic gas semltime quartz glass, opaque quartz glass, quartz glass, quartz glass, semiconductor electric light source with quartz glass.
- Q:The quartz ceramic crucible melting quartz crucible
- Because of the use of extremely harsh conditions, the crucible of purity, strength, appearance defects, internal quality, high temperature performance, thermal shock stability and dimensional accuracy has very strict requirements.
