Q: How to improve the quality of transparent layer of quartz crucible used for monocrystalline silicon: The quartz crucible used for monocrystalline silicon is generally divided into 3 layers: the outermost bubble area, the middle transparent layer (ideally without bubbles), and the innermost layer coating.

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: 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: 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: 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?: Yes, once a quartz crucible has been used, it will crack or break even after high temperature and cooling. And the single crystal drawing requires a high-purity quartz crucible.

Q: What are the main differences between the corundum crucible and the quartz crucible?: HF can not contact, high temperature, easy and caustic alkali carbonate reaction and alkali metal; quartz crucible suitable for K2S2O7, KHSO4 and Na2S207 as flux melted samples (first drying at 212 degrees) as flux sample; quartz brittle, easily broken, use caution; in addition to Hf, the ordinary dilute inorganic acid can be used as cleaning liquid.

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.

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.
