Q:Quartz products are mainly used in photovoltaic and semiconductor industry which links, please expert pointing!

The photovoltaic industry with loaded fixture quartz wafer, the amount is large, our students also have automatic quartz boat loading machine.

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: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 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: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 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 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?

Ceramic crucible: heat of 1200 degrees; suitable for K2S2O7 acid melt samples.; generally can not be used with NaOH, Na2O2, Na2CO3 and other alkaline substances as flux melting, in order to avoid corrosion of porcelain crucible. Porcelain crucible and hydrofluoric acid exposure; porcelain crucible can dilute hydrochloric acid washing boiling cleaning.

Q:Why are fused quartz transparent and opaque?

China referred to as quartz glass, press process, use and appearance to the classification, such as transparent fused quartz glass, fused quartz glass, quartz glass, synthetic gas semltime quartz glass, opaque quartz glass, quartz glass, quartz glass, semiconductor electric light source with quartz glass.
