Q:What are the sizes of arc quartz crucibles?
Quartz brittle, easy to break, use should pay attention to. 5. except for Hf, ordinary dilute inorganic acid can be used as cleaning solution. Porcelain crucible 1. can heat 1200 degrees or so, use 2. suitable for K2S2O7 and other acidic substances melting sample. 3., generally can not be used for NaOH, Na2O2, Na2CO3 and other alkaline substances for melting flux, so as not to corrode the porcelain crucible. Porcelain crucibles shall not be in contact with hydrofluoric acid. 4. porcelain crucible can be diluted hydrochloric acid boiling cleaning. Corundum crucible, corundum crucible and 1. corundum crucible are made of porous fused alumina, which is compact and resistant to melting.
Q:Can quartz crucibles be used as ROI for fluorine compounds?
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.
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?
Corundum crucible: corundum crucible is composed of porous fused alumina, hard and refractory; corundum crucible for melting flux samples with anhydrous Na2C03 and some alkaline substances, not suitable for use in Na 202 and NaOH strong alkaline substances and acidic substances as flux (as K2S 207) melt sample.
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: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: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 crucible is used to melt solid caustic soda?Why not quartz crucibles?
Iron. React with ceramic or glass silica ash
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?
Quartz crucibles should be noted for use:(1) HF can not contact, can not be used for heating, carbonate and oxide caustic alkali and alkaline earth metal.(2) the quartz is fragile and easy to break, so we should pay attention to it.(3) except HF, the ordinary dilute inorganic acid of quartz glass crucible can be used as cleaning liquid.4. Heating calcium oxide or calcium hydroxide at high temperature, usually using iron crucible.
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.
