  • METHOD FOR PURIFICATION OF SILICON
    Publication number: 20200407874
    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.
    Type: Application

  • Cascading purification
    Patent number: 8540958
    Abstract: The present invention provides a method of purifying a material using a cascading dissolution and washing process. The dissolution and washing processes can contain single or multiple stages. Water and dissolving chemicals are recycled through the process towards the beginning of the process.
