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?

Answer:

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
The coating has the effect of increasing the crystallization rate without increasing the cost and is more impractical
First of all, the main source of oxygen is the fusion of silicon and quartz crucible, 99% of oxygen volatilization, and 1% of the growth of single crystal into the silicon bar, so it has nothing to do with the coating, unless the crucible is not, but not possible
