The Process Of Mining Silica

How silicon is made material making history used

The Manufacturing Process The basic process heats silica and coke in a submerged electric arc furnace to high temperatures High temperatures are required to produce a reaction where the oxygen is removed leaving behind silicon This is known as a reduction process In this process metal carbides usually form first at the lower temperatures
