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:Is the quartz crucible drawn by monocrystalline silicon disposable?

One must, one pot, 3000 pieces! Or made in China?

Q:What are the main differences between the corundum crucible and the quartz crucible?

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.

Q:External surface macular problem of arc type quartz crucible

After cleaning the pot can not see the macula, and heated to about three, Baidu appeared macular, because the reason is simple: no cleaning.

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:A brief introduction to quartz crucibles

HF can not contact, high temperature, easy and effect of carbonate caustic alkali metal.

Q:What happens when carbon carbon crucibles are cracked?

The R corner is part of gravity and expansion forces;

Q:What are the functional features of quartz crucibles?

In addition to HF, quartz glass crucibles are usually diluted with inorganic acids, which can be used as cleaning solutions.

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 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.
