Q: How to improve the quality of transparent layer of quartz crucible used for monocrystalline silicon: The higher the quality of the transparent layer, which is the bubble less, more uniform thickness, R thickness of the thicker crystal: 1. in straightening isolated bubble layer bubbles into the soluble silicon in 2, the province will have a layer of transparent bubble burst into tiny particles of silica. The bubble burst into soluble silicon is the most direct impact on the single drum off, the second is the increase of oxygen content

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

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: 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: 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: 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: After cleaning the pot can not see the macula, and heated to about three, Baidu appeared macular, because the reason is simple: no cleaning.

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?: 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?: In addition to HF, quartz glass crucibles are usually diluted with inorganic acids, which can be used as cleaning solutions.
