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 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?
After a long period of use, its silicon vapor corroded the edges of the carbon and carbon parts;
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: A brief introduction to quartz crucibles
HF can not contact, high temperature, easy and effect of carbonate caustic alkali metal.
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: What are the sizes of arc quartz crucibles?
Quartz crucible can be used below 1650 degrees. It is divided into two kinds: transparent and opaque. The translucent quartz crucible fabricated by arc method is a basic material for developing large scale integrated circuits. Today, the world's semiconductor industry developed countries have replaced the small transparent quartz crucible with this crucible. It has the advantages of high purity, strong heat resistance, large size, high precision, good heat insulation, energy saving, stable quality and so on.
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: Can quartz crucibles be used as ROI for fluorine compounds?
Quartz crucible can be used below 1650 degrees. It is divided into two kinds: transparent and opaque. The translucent quartz crucible fabricated by arc method is a basic material for developing large scale integrated circuits.
Q: What are the functional features of quartz crucibles?
Functional features of quartz crucibles:1, quartz crucible can be used below 1450 degrees, divided into two kinds of transparent and opaque.2, can not touch the HF and, at high temperature, easy and caustic alkali carbonate reaction and alkali metal.
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.
