Abstract
A method can include reducing a silica starting material to produce a first quantity of at least metallurgical grade silicon and a second quantity of silica comprising elemental carbon doping, wherein the silica starting material is reduced in the presence of a carbonaceous reducing agent. A silica material can be a silica material as prepared according to the method.
Claims12
A method comprising:
- reducing a silica starting material in a furnace to produce silicon with an elemental purity of about 99% and silica fumes comprising between 2-10% carbon by mass and 90-98% silica by mass, wherein the silica starting material is reduced in the presence of a carbonaceous reducing agent, wherein the furnace is not cleaned between reducing the silica starting material and reducing a second silica starting material.
