White Quartz Crucible

Q: How to improve the quality of transparent layer of quartz crucible used for monocrystalline silicon: The quartz crucible used for monocrystalline silicon is generally divided into 3 layers: the outermost bubble area, the middle transparent layer (ideally without bubbles), and the innermost layer coating.

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 crucible is used to melt solid caustic soda?Why not quartz crucibles?: Do not use ceramic crucibles or quartz crucibles. Use metal crucibles, preferably with silver cruciblesThe quartz crucible reacts to form the sodium silicate (2NaOH+SiO2=Na2SiO3+H2O) ceramic crucible

Q: What happens when carbon carbon crucibles are cracked?: The R corner is part of gravity and expansion forces;

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

Q: A brief introduction to quartz crucibles: HF can not contact, high temperature, easy and effect of carbonate caustic alkali metal.

Q: External surface macular problem of arc type quartz crucible: We often re wash the modified products, never found this problem. There may be cold coating or packaging operations problems

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: 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 functional features of quartz crucibles?: Quartz is fragile and easy to break, so we should pay attention to it.
