Q:What are the functional features of quartz crucibles?: Quartz is fragile and easy to break, so we should pay attention to it.

Q:What's the difference between a quartz crucible and a porcelain crucible?: The quartz crucible and the ceramic crucible have different temperature resistance, and the acid and alkali are different

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:Is the quartz crucible drawn by monocrystalline silicon disposable?: One must, one pot, 3000 pieces! Or made in China?

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: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 happens when carbon carbon crucibles are cracked?: If the whole crucible is used, the external force of the crucible will cause the fiber damage of the carbon crucible when the quartz crucible is taken.In addition, the carbon carbon crucible may cause cracks during the fabrication of the preform.

Q:Can the quartz crucible react with calcium oxide or calcium hydroxide at high temperature?: The main component of the quartz crucible is SiO2. Silica is an atomic crystal with a high boiling point, so it can be used as a crucible material.

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: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

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.
