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: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: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 is white and transparent, and the opal crucible is used below 1200 degrees. The transparent crucible is used below 1400 degrees. The ceramic crucible is used at 1400-1600 degreesThe quartz crucible is resistant to acid and alkali, but hydrofluoric acid is not availableCeramic crucible does not resist strong alkali

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: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: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?

The quartz glass crucible is usually used for the production of monocrystalline silicon, and the production temperature of single crystal is 1450 degrees

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.
