- 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: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: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: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:What happens when carbon carbon crucibles are cracked?
- The R corner is part of gravity and expansion forces;
- 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 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: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.
We are a high-tech enterprise specialized in the production of semiconductor monocrystal silicon and solar grade high purity quartz crucibles. One of the greatest advantages of us is that we enjoy more than 100 solar grade monocrystalline furnaces in China,which can help to test the stability of our quartz crucibles. The sales volume of our solar grade quartz crucibles has always been in the top 3 among other manufacturers since 2007.
