Q:Quartz products are mainly used in photovoltaic and semiconductor industry which links, please expert pointing!

Quartz can be used in many industriesYou should say that the PV and semi industry should be polycrystalline silicon or monocrystalline siliconThe manufacture of quartz products is first made into quartz powder, which can be used as quartz glass tubes, quartz plates, crucibles and so onThe crucible is very demanding, because it's Gao ChunshaThe crucible is stable because of the physical properties of the quartz material and can be used to refine polycrystalline silicon - monocrystalline siliconThe industry itself has recently come into contact, and it should be said that the prospects for development are good

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:Can porcelain crucible, quartz crucible and alumina crucible be filled with aluminium hydroxide?

Quartz glass crucible can be used below 1450 degrees. It is divided into two kinds: transparent and opaque

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: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: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: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: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: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.
