Issues with the H2 to TCS ratio in the reduction reaction of the modified Siemens method
Thread Content
I would like to consult professionals in the field of reduction: Is it feasible to control the popcorning rate of silicon rods by adjusting the ratio of H2 to TCS? What is an appropriate value for its molar ratio?
It’s really difficult to give a clear answer to this question, as popcorn production is related to many factors: the proportions used, flow rates, pressure, and the interactions between these various factors. It’s best to try different approaches on your own. Besides, as long as the popcorn isn’t too large, it has little impact on the quality of the product
For popcorn alone, the impact of the ratio is minor
Reply to 2# maxwell_112: Too much popcorn results in insufficient density of the silicon rods, which easily leads to low current alarms. I don’t know if you’ve encountered it or not.
Relying solely on adjusting the proportions to address the problem with cauliflower will not yield ideal results; what’s key is the volume of gas and its distribution.
