- Q:What are the functional features of quartz crucibles?
- Quartz is fragile and easy to break, so we should pay attention to it.
- 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:Is the quartz crucible drawn by monocrystalline silicon disposable?
- The used quartz crucibles have been contaminated. Therefore, quartz crucibles used for single crystal drawing are disposable
- Q:What are the main differences between the corundum crucible and the quartz crucible?
- HF can not contact, high temperature, easy and caustic alkali carbonate reaction and alkali metal; quartz crucible suitable for K2S2O7, KHSO4 and Na2S207 as flux melted samples (first drying at 212 degrees) as flux sample; quartz brittle, easily broken, use caution; in addition to Hf, the ordinary dilute inorganic acid can be used as cleaning liquid.
- Q:The quartz ceramic crucible melting quartz crucible
- Quartz ceramic crucible is a key component of the solar polysilicon ingot furnace, it acts as a container for loading of polycrystalline material to high temperature is over 1500 DEG C under more than 50 hours of continuous work, to melt to produce to solar polysilicon ingot.
- Q:What happens when carbon carbon crucibles are cracked?
- The R corner is part of gravity and expansion forces;
- 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: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:What crucible is used to melt solid caustic soda?Why not quartz crucibles?
- Iron. React with ceramic or glass silica ash
- 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.
