RE:Fumed silica byproduct silica fume

[developbc]

@cargo The thing about silica fume is it can be converted to Silicon Carbide by heating it with graphite at 1500°C (2730°F). My guess is that if the silica fume is pure enough coming from the Purevap process this could be another avenue that $HPQ + $PYR could investigate down the road.

@cargo Sweet, just found the info I was looking for, the purity of the silica fume (SiO2) needs to be high-grade based on the link below.

My hunch is since we will be producing 3N-4N silicon in one step, we will also be producing a very high purity byproduct. $HPQ "SiO2 ≥ 96.5% high-grade microsilica can be used for the production of silicon carbide and other high-grade refractory materials"
