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 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: What happens when carbon carbon crucibles are cracked?: The R corner is part of gravity and expansion forces;

Q: Quartz products are mainly used in photovoltaic and semiconductor industry which links, please expert pointing!: Quartz in these two sectors: 1, mainly used in the preparation of high purity quartz crucible, when polysilicon ingots and crystal growth will be used in high purity quartz crucible, which is the main purpose of the quartz crucible in the photovoltaic industry, a large amount of cut. 2. High-purity quartz rings are needed in the polysilicon reduction furnace.

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?: First of all, the main source of oxygen is the fusion of silicon and quartz crucible, 99% of oxygen volatilization, and 1% of the growth of single crystal into the silicon bar, so it has nothing to do with the coating, unless the crucible is not, but not possible

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

Q: Why are fused quartz transparent and opaque?: China referred to as quartz glass, press process, use and appearance to the classification, such as transparent fused quartz glass, fused quartz glass, quartz glass, synthetic gas semltime quartz glass, opaque quartz glass, quartz glass, quartz glass, semiconductor electric light source with quartz glass.

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: 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.
