It's my understanding that reduction of silica to metallurgical silicon, which is done in an arc furnace using carbon as the reductant: SiO2 + 2C --> Si + 2 CO is best done with charcoal, not coal, due to the porous microstructure of charcoal more effectively interacting with silicon monoxide vapor. So not only is coal not needed, it's not even the best feedstock for this process. |
