3.It can be customized
4.Material: quartz glass

Application of Sized Quartz Crucible

1.Temperature :

Softening point temperature of about 1730 degrees Celsius ,1100 degrees Celsius in a long time use ,short-term maximum temperature up to 1450 degrees Celsius ;

2.Anti-corrosion :

In addition to hydrofluoric acid ,is an almost non-acid and other substances a chemical reaction ,especially in the high temperature chemical stability is in any other engineering materials can not be compared;

3.Thermal stability :

The thermal expansion coefficient of quartz galss ,is extremely small ,able to withsand drastic temperature changes ;

4.Transmittance good performance :

Quartz glass in the entire ultraviolet to infrared spectral bands have a good light transmission properties, visible light transmittance of 93% or more ,especially in the ultraviolet spectral region ,the largest up to 80% or more transmittance.

Sized Quartz Crucible

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 crucible is used to melt solid caustic soda?Why not quartz crucibles?: Do not use ceramic crucibles or quartz crucibles. Use metal crucibles, preferably with silver cruciblesThe quartz crucible reacts to form the sodium silicate (2NaOH+SiO2=Na2SiO3+H2O) ceramic crucible

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: 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: 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: A brief introduction to quartz crucibles: HF can not contact, high temperature, easy and effect of carbonate caustic alkali metal.

Q: External surface macular problem of arc type quartz crucible: We often re wash the modified products, never found this problem. There may be cold coating or packaging operations problems

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?: The long-term use of the crucible temperature is 1100 degrees, but pulling when the stone is outside, so can be used for a long time. The crucible will deform about 1300 degrees. 1100 degrees without deformation.

Q: What are the functional features of quartz crucibles?: In addition to HF, quartz glass crucibles are usually diluted with inorganic acids, which can be used as cleaning solutions.
