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?: A metal crucible can not be used with a porcelain crucible, because the reaction of caustic soda and silicate can not be used in ceramics

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

Q: Is the quartz crucible drawn by monocrystalline silicon disposable?: The used quartz crucibles have been contaminated. Therefore, quartz crucibles used for single crystal drawing are disposable

Q: Why are fused quartz transparent and opaque?: Quartz glass is a kind of special glass containing only single silica component. Because of the type of technology, raw materials, quartz glass, glass, often called foreign silicate quartz glass, fused silica, fused quartz, synthetic fused silica, and no clear concept of transparent, translucent, opaque quartz.

Q: A brief introduction to quartz crucibles: Quartz crucible can be used below 1450 degrees. It is divided into two kinds: transparent and opaque. The translucent quartz crucible fabricated by arc method is the basic material for drawing large diameter monocrystalline silicon and developing large-scale integrated circuits. Today, the world's semiconductor industry developed countries have replaced the small transparent quartz crucible with this crucible. He has high purity and strong heat resistance, large size high precision, good heat insulation, energy saving, stable quality etc..

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?: Quartz crucibles should be noted for use:(1) HF can not contact, can not be used for heating, carbonate and oxide caustic alkali and alkaline earth metal.(2) the quartz is fragile and easy to break, so we should pay attention to it.(3) except HF, the ordinary dilute inorganic acid of quartz glass crucible can be used as cleaning liquid.4. Heating calcium oxide or calcium hydroxide at high temperature, usually using iron crucible.

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
