Is the cold hydriding start-up silicon powder pre-added? What are the sequence and conditions for feeding the raw materials?
It is added to the reactor in advance, then heated, and other materials are introduced

It’s just added to the dryer first and then put into the reactor; there’s nothing special about it. After that, once the reactor and dryer are filled with silicon powder, synchronous activation drying can be carried out; of course, it is required that the silicon powder not be too moist.
Agree with the person above! I’ve learned it!
