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?: 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?: Iron. React with ceramic or glass silica ash

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: 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: 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: What are the sizes of arc quartz crucibles?: Quartz brittle, easy to break, use should pay attention to. 5. except for Hf, ordinary dilute inorganic acid can be used as cleaning solution. Porcelain crucible 1. can heat 1200 degrees or so, use 2. suitable for K2S2O7 and other acidic substances melting sample. 3., generally can not be used for NaOH, Na2O2, Na2CO3 and other alkaline substances for melting flux, so as not to corrode the porcelain crucible. Porcelain crucibles shall not be in contact with hydrofluoric acid. 4. porcelain crucible can be diluted hydrochloric acid boiling cleaning. Corundum crucible, corundum crucible and 1. corundum crucible are made of porous fused alumina, which is compact and resistant to melting.

Q: Can the quartz crucible react with calcium oxide or calcium hydroxide at high temperature?: The main component of the quartz crucible is SiO2. Silica is an atomic crystal with a high boiling point, so it can be used as a crucible material.

Q: How much fire resistance is quartz crucible?: It depends on the raw material used in your crucible. It is usually above more than 1100 degrees, but it must be guaranteed to not be crystallized

Q: What are the functional features of 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.

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.
