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: 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 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!
The photovoltaic industry with loaded fixture quartz wafer, the amount is large, our students also have automatic quartz boat loading machine.
Q: Is the quartz crucible drawn by monocrystalline silicon disposable?
One must, one pot, 3000 pieces! Or made in China?
Q: A brief introduction to quartz crucibles
HF can not contact, high temperature, easy and effect of carbonate caustic alkali metal.
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: 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: Can quartz crucibles be used as ROI for fluorine compounds?
Ceramic crucible: heat of 1200 degrees; suitable for K2S2O7 acid melt samples.; generally can not be used with NaOH, Na2O2, Na2CO3 and other alkaline substances as flux melting, in order to avoid corrosion of porcelain crucible. Porcelain crucible and hydrofluoric acid exposure; porcelain crucible can dilute hydrochloric acid washing boiling cleaning.
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.
