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:External surface macular problem of arc type quartz crucible
After cleaning the pot can not see the macula, and heated to about three, Baidu appeared macular, because the reason is simple: no cleaning.
Q:How to improve the quality of transparent layer of quartz crucible used for monocrystalline silicon
The higher the quality of the transparent layer, which is the bubble less, more uniform thickness, R thickness of the thicker crystal: 1. in straightening isolated bubble layer bubbles into the soluble silicon in 2, the province will have a layer of transparent bubble burst into tiny particles of silica. The bubble burst into soluble silicon is the most direct impact on the single drum off, the second is the increase of oxygen content
Q:What are the functional features of quartz crucibles?
Functional features of quartz crucibles:1, quartz crucible can be used below 1450 degrees, divided into two kinds of transparent and opaque.2, can not touch the HF and, at high temperature, easy and caustic alkali carbonate reaction and alkali metal.
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?
HF can not contact, high temperature, easy and caustic alkali carbonate reaction and alkali metal; quartz crucible suitable for K2S2O7, KHSO4 and Na2S207 as flux melted samples (first drying at 212 degrees) as flux sample; quartz brittle, easily broken, use caution; in addition to Hf, the ordinary dilute inorganic acid can be used as cleaning liquid.
Q:Is the quartz crucible drawn by monocrystalline silicon disposable?
One must, one pot, 3000 pieces! Or made in China?
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?
People accustomed to using "quartz" such a simple words to name this material, it is absolutely wrong, because "quartz" is a generic term silica crystalline, and glassy silica in physical and chemical properties are different.
Q:Quartz products are mainly used in photovoltaic and semiconductor industry which links, please expert pointing!
Quartz in these two sectors: 1, mainly used in the preparation of high purity quartz crucible, when polysilicon ingots and crystal growth will be used in high purity quartz crucible, which is the main purpose of the quartz crucible in the photovoltaic industry, a large amount of cut. 2. High-purity quartz rings are needed in the polysilicon reduction furnace.
