Chemicals Quartz Crucible

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: 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: 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: 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.

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: A brief introduction to quartz crucibles: In addition to HF, ordinary dilute inorganic acids can be used as cleaning solutions. Quartz crucibles used for drawing monocrystalline silicon in China are 18 inches and 20 inches 22 inches. There are also 22 or more crucibles used by manufacturers. At present, the crucible technology produced by large crucible manufacturers in China is quite mature. Its production and use of raw materials, quartz sand imported by the United States and Norway high purity quartz sand two. There are also small factories using homemade materials. The quartz crucibles produced by their raw materials have certain influence on the stability of the drawn monocrystalline silicon.The current production of crucible coating technique has been used by most manufacturers is in ordinary quartz sand solution for crucible surface coated with a layer of two barium oxide solution so as to form a dense layer, the dense layer can prevent the silicon and silicon high temperature quartz crucible drawing process to improve reaction rate.

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: Can quartz crucibles be used as ROI for fluorine compounds?: 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.

Q: What are the functional features of 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.
