Abstract:
The present invention relates to the purification of silicon. The present invention provides a method for purification of silicon. The method includes recrystallizing starting material-silicon from a molten solvent comprising aluminum to provide final recrystallized-silicon crystals. The method also includes washing the final recrystallized-silicon crystals with an aqueous acid solution to provide a final acid-washed-silicon. The method also includes directionally solidifying the final acid-washed-silicon to provide final directionally solidified-silicon crystals.

Claim (Index 5):
The method of  claim 1 , wherein cooling the first molten mixture comprises forming first silicon crystals and a third mother liquor, wherein the recrystallizing further comprises:\n separating the first silicon crystals from the third mother liquor; contacting the separated first silicon crystals and a first mother liquor to provide a second mixture; melting the second mixture to provide a second molten mixture; cooling the second molten mixture to form second silicon crystals and a second mother liquor; separating the second silicon crystals from the second mother liquor; contacting the second silicon crystals with a first solvent metal comprising the aluminum to provide a third mixture; melting the third mixture to provide a third molten mixture; cooling the third molten mixture to form the recrystallized silicon crystals and the first mother liquor; and separating the recrystallized silicon crystals from the first mother liquor, wherein at least a portion of the solvent metal in the step of contacting the starting material silicon with the solvent metal comprises the first mother liquor.
