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

Today, the world semiconductor industry in developed countries has used this crucible instead of transparent quartz crucible is small. He has high purity and strong heat resistance, large size high precision, good heat insulation, energy saving, stable quality and other advantages.

Q:Is the quartz crucible drawn by monocrystalline silicon disposable?

One must, one pot, 3000 pieces! Or made in China?

Q:The quartz ceramic crucible melting quartz crucible

Because of the use of extremely harsh conditions, the crucible of purity, strength, appearance defects, internal quality, high temperature performance, thermal shock stability and dimensional accuracy has very strict requirements.

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: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: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: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: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.
