Abstract
A method of the producing nanocrystalline silicon particulate from a silicate source includes removing contaminants, such as organics and heavy metals, and alumina from the silicate source by treating the silicate source with first and second acidic leaching solutions to form a first intermediate product. The first intermediate product is then reduced by reacting with a magnesium vapor to provide porous magnesiated silicon particulates as a second intermediate product. The second intermediate product is treated with a third leaching solution to remove magnesium and magnesium containing compounds form the second intermediate to thereby provide a third intermediate. The third intermediate is treated with a fourth leaching solution for removing remnant silica to thereby provide nanocrystalline porous silicon particles.
