- Q: How to improve the quality of transparent layer of quartz crucible used for monocrystalline silicon
- In order to improve the quality of the transparent quartz crucible layer three: 1: use of raw materials, it is the monopoly of the uni quartz sand.2. vacuum arc furnace production method of vacuum and high pure health, it is important to you in one process pay attention to detail is no good.3., the production process and temperature, etc., these are the details of the process, such as temperature, cooling time ah...
- Q: Can porcelain crucible, quartz crucible and alumina crucible be filled with aluminium hydroxide?
- The translucent quartz crucible made by arc method is the basic material for drawing large diameter monocrystalline silicon and developing large-scale integrated circuit
- Q: What crucible is used to melt solid caustic soda?Why not quartz crucibles?
- A metal crucible can not be used with a porcelain crucible, because the reaction of caustic soda and silicate can not be used in ceramics
- 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: 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: What are the main differences between the corundum crucible and the quartz crucible?
- Corundum crucible: corundum crucible is composed of porous fused alumina, hard and refractory; corundum crucible for melting flux samples with anhydrous Na2C03 and some alkaline substances, not suitable for use in Na 202 and NaOH strong alkaline substances and acidic substances as flux (as K2S 207) melt sample.
- Q: External surface macular problem of arc type quartz crucible
- In order to solve this problem, you can start from two aspects: the 1 is the melting of sandblasting, cutting and transportation and storage process, do not touch the pollutants; such as dirty gloves, equipment oil, touch, dust, etc.. 2 is pickling. Hydrofluoric acid blister for a few minutes, rinse with deionized water, water resistivity is higher than 12 trillion, 14 or 16 better.
- 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.
- 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: Can quartz crucibles be used as ROI for fluorine compounds?
- Ceramic crucible: heat of 1200 degrees; suitable for K2S2O7 acid melt samples.; generally can not be used with NaOH, Na2O2, Na2CO3 and other alkaline substances as flux melting, in order to avoid corrosion of porcelain crucible. Porcelain crucible and hydrofluoric acid exposure; porcelain crucible can dilute hydrochloric acid washing boiling cleaning.
