Quartz Glass Crucible

1.Made of quartz

2.For multicrystalline silicon solar

3.Long life,no crack

 

Quartz Glass Crucible

Fused silica crucible crucible is a kind of combined product,made of  fused silica (quartz glass) as raw material.With small thermal expansion coefficient, good thermal shock stability, good resistance to chemical attack (in particular for acid and chlorine), resistance to erosion, big viscosity at high temperature, high strength, low thermal conductivity. Mainly used in water gap, lift tube,powder metallurgy and chemical industry.In glass industry it is used as the material barrel ect.

 

The features of fused quartz crucible: ultra-low expansion coefficient, high thermal stability, when 1000 °C water cooling.no cracking; long service life, especially for thermal shock; fewer impurities, high quality of burning of rare earth; fast heat conduction, low energy consumption, low weight,labor intensity reduction;wall light, non-stick powder, loss of rare-earth throw reduction. Frequency of use:more than 100 times! This item is suitable for multicrystalline silicon solar

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 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:What are the functional features of quartz crucibles?
Quartz is fragile and easy to break, so we should pay attention to it.
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:A brief introduction to quartz crucibles
HF can not contact, high temperature, easy and effect of carbonate caustic alkali metal.
Q:Can porcelain crucible, quartz crucible and alumina crucible be filled with aluminium hydroxide?
Quartz glass crucible can be used below 1450 degrees. It is divided into two kinds: transparent and opaque
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:Quartz products are mainly used in photovoltaic and semiconductor industry which links, please expert pointing!
Quartz in these two sectors: 1, mainly used in the preparation of high purity quartz crucible, when polysilicon ingots and crystal growth will be used in high purity quartz crucible, which is the main purpose of the quartz crucible in the photovoltaic industry, a large amount of cut. 2. High-purity quartz rings are needed in the polysilicon reduction furnace.
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:At present, the quartz crucible used in Czochralski silicon is used to make use of barium coating, but how does the oxygen content rise when the coating react with the silicon melt?
Oxygen reduction process can be resolved by other processes, oxygen control within 0.8E17 process, the current strong monocrystalline silicon enterprises, has been very easyIn addition, a message can be disclosed that there are large enterprises in the development of new coatings, because barium coating process is foreign patent, the Chinese people are in Tort
