- Q:What are the functional features of quartz crucibles?
- Quartz is fragile and easy to break, so we should pay attention to it.
- Q:Is the quartz crucible drawn by monocrystalline silicon disposable?
- One must, one pot, 3000 pieces! Or made in China?
- 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?
- The coating has the effect of increasing the crystallization rate without increasing the cost and is more impractical
- 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:What happens when carbon carbon crucibles are cracked?
- The R corner is part of gravity and expansion forces;
- Q:How much fire resistance is quartz crucible?
- It depends on the raw material used in your crucible. It is usually above more than 1100 degrees, but it must be guaranteed to not be crystallized
- 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 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: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.
- 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...
