Q: How to improve the quality of transparent layer of quartz crucible used for monocrystalline silicon
In order to improve the quality of the transparent quartz crucible layer three: 1: use of raw materials, it is the monopoly of the uni quartz sand.2. vacuum arc furnace production method of vacuum and high pure health, it is important to you in one process pay attention to detail is no good.3., the production process and temperature, etc., these are the details of the process, such as temperature, cooling time ah...
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: 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?
The coating has the effect of increasing the crystallization rate without increasing the cost and is more impractical
Q: A brief introduction to quartz crucibles
The quartz crucible is suitable for melting samples with K2S2O7, KHSO4 as flux, and using Na2S207 (first drying at 212 degrees) to treat samples with flux.
Q: External surface macular problem of arc type quartz crucible
In order to solve this problem, you can start from two aspects: the 1 is the melting of sandblasting, cutting and transportation and storage process, do not touch the pollutants; such as dirty gloves, equipment oil, touch, dust, etc.. 2 is pickling. Hydrofluoric acid blister for a few minutes, rinse with deionized water, water resistivity is higher than 12 trillion, 14 or 16 better.
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 are the sizes of arc quartz crucibles?
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. Today, the world's semiconductor industry developed countries have replaced the small transparent quartz crucible with this crucible. It has the advantages of high purity, strong heat resistance, large size, high precision, good heat insulation, energy saving, stable quality and so on.
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?
It has the advantages of high purity, strong heat resistance, large size, high precision, good heat insulation, energy saving, stable quality and so on; and not HF contact, high temperature, easy and caustic alkali carbonate reaction and alkali metal; quartz crucible suitable for K2S2O7, KHSO4 and Na2S207 as flux melted samples (the first in 212 the degree of drying) as flux sample; quartz brittle, easily broken, use caution; in addition to Hf, the ordinary dilute inorganic acid can be used as a cleaning fluid. 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.
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.
