    摘要： GERMANIUM HAVING A PURITY OF THE ORDER OF 10**12 UNCOMPENSATED ELECTRICALLY ACTIVE IMPURITY ATOMS PER CUBIC CENTIMETER THEREOF IS PROCESSED TO PRODUCE HYPERPURE GERMANIUM HAVING A PURITY, REPRESENTED BY THE ORDER OF 10**10 CONCOMPENSATED IMPURITY ATOMS PER CUBIC CENTIMETER THEREOF, BY MELTING COMMERCIALLY AVAILABLE, HIGH-PURITY GERMANIUM OF THE AFOREMENTIONED IMPURITY LEVEL IN A REACTION CHAMBER WHEREIN THE MOLTEN GERMANIUM HAS A SUBSTANTIAL PORTION OF THE SURFACE THEREOF IN CONTACT WITH THE AMBIENT ATMOSPHERE AND GROWING A CRYSTALLINE INGOT THEREFROM BY FRACTIONAL CRYSTALLIZATION WHILE PURE DRY NITROGEN IS PASSED THROUGH THE REACTION CHAMBER.

    摘要： A process is provided for the production of elemental silicon from a silica containing glass melt including contacting the glass with a metal capable of undergoing a bimolecular reaction between the glass and metal at elevated temperature to reduce the oxidation state of the silicon in the glass to elemental silicon while oxidizing the metal, collecting, and optionally separating the elemental silicon. Similarly, elemental germanium is produced from a germania-containing glass.
