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 13):
The method of  claim 12 , wherein the multiplicity of blocks of the ingot comprise a grid;\n wherein the exterior shape of the crucible approximately matching the interior shape of the furnace allows the generation of a larger number of blocks than can be generated from the furnace using a corresponding crucible with a square shape; wherein the interior shape of the furnace comprises an approximately round shape; and wherein a perimeter of the crucible comprises approximately eight major sides, wherein the eight major sides comprise two sets of approximately opposing longer sides of approximately equal length, and two sets of approximately opposing shorter sides of approximately equal length, wherein the longer sides alternate with the shorter sides.
