As you doubtless know, the standard process for reducing silica to produce metallurgical grade silicon is carbonic reduction below 2000OC. So, unless you absolutely need the specific form of silicon that forms under these conditions, this process sounds like mowing the lawn using nail scissors.
More information about your final requirement, please.
Reducing silica to produce metallurgical grade silicon is one of our goals. We intend to use a new form of microwaves to achieve it at God knows what temperature.
We were wondering if someone did this before with conventional and multimode microwaves. The expected results with our technology are to improve the yield and to obtain a much more uniform temperature distribution throughout the mass.
That reads as if you are planning to use maser-driven dissociation at temperature. That means you will need to separate the droplets of Si and the O2 before the mix falls below the recombination temperature. That will be challenging.
From my perspective (I use both ultrapure silicon and silica) the benefit would be if this separation also removes the other impurities, allowing subsequent processing to be simplified. However, I'm not knowledgeable enough to say whether this should be anticipated. Is that your objective (and do you have reasons to expect this)?
"... We intend to use a new form of microwaves ..."
New form of microwaves? New form?
You're kidding, right?
You can vary the frequency, the polarisation and the amplitude, each and all of which are done every single day, so what combination comprises the 'new form'? Which one hasn't been done before?
