    摘要: Embodiments of the present invention relate to a process for obtaining silicon crystals from silicon. The method includes contacting silicon powder with a solvent metal to provide a mixture containing silicon, melting the silicon under submersion to provide a first molten liquid, contacting the first molten liquid with a first gas to provide dross and a second molten liquid, separating the dross and the second molten liquid, cooling the second molten liquid to form first silicon crystals and a first mother liquid and separating the first silicon crystals and the first mother liquid.

    摘要: A method for purifying silicon wherein silicon is crystallized from a solvent metal. The method comprises the steps of providing a molten liquid containing silicon, a solvent metal and impurities, cooling the molten liquid to form first silicon crystals and a first mother liquor, separating the first silicon crystals from the first mother liquor, contacting the first silicon crystals with compound which will dissolve the first mother liquor and separating the washed crystals from the wash solution.

    摘要: The present invention relates to a method of purifying a material using a metallic solvent. The present invention includes a method of purifying silicon utilizing a cascade process. In a cascade process, as the silicon moves through the purification process, it contacts increasingly pure solvent metal that is moving through the process in an opposite direction.
