    Abstract: WHICH ARE REMOVED OVERHEAD. THE REDUCIBLE ALKALI METAL COMPOUND MAY BE AN ALKALI METAL CARBONATE, AN ALKALI METAL HYDROXIDE, AND AN ALKALI METAL COMPOUND (SUCH AS BORAX) HAVING A NEGATIVE GROUP CONTAINING AN AMPHOTERIC METAL WHICH LATTER COMPOUND PROVIDES UPON REDUCTION THE ALKALI METAL VAPOR AND THE AMPHOTERIC METAL IN A REDUCED SOLID ELECTRICALY-CONDUCTIVE FORM. THE LATTER ALKALI METAL-AMPHOTERIC METAL COMPOUNDS IN PROVIDING ELECTRICALLY-CONDUCTIVE SOLID RESIDUE UPON REDUCTION ARE PROCESSIBLE IN BEDS OF VARYING TYPES.

    METHOD FOR PRODUCING ELEMENTAL ALKALI METAL FROM A REDUCIBLE ALKALI METAL COMPOUND IN A CARBOTHERIMIC REDUCTION FURNACE INVOLVING, IN A PREFERRED EMBODIMENT, PASSING A DOWNWARDLY MOVING BED THROUGH A HEATING ZONE OF THE FURNACE WITH A REDUCIBLE ALKALI METAL COMPOUND AND A CARBON REDUCING METAL DISPERSED IN THE BED IN PARTICLES SMALLER THAN THE ELECTRICALLY-CONDUCTIVE BALLS WITH THE REDUCIBLE ALKALI METAL COMPOUND COMPRISING ON A WEIGHT BASIS LESS THAN 50% OF THE BED, HEATING THE BED WITH ELECTRIC CURRENT TO A TEMPERATURE IN THE RANGE OF ABOUT 900*C. TO ABOUT 1500*C. TO EFFECT REDUCTION OF THE ALKALI METAL COMPOUND TO PRODUCE ALKALI METAL VAPORS

    Abstract: A PROCESS FOR THE PRODUCTION OF A DIHALOBORANE-CONTAINING STREAM WHICH INVOLVES MIXING AND REACTING A BORON TRIHALIDE-CONTAINING STREAM WITH A HOTTER STREAM OF HYDROGEN, TYPICALLY HAVING A TEMPERATURE IN EXCESS OF 1500*C., TO PRODUCE A DIHALOBORANE-CONTAINING PRODUCT STREAM AND PRECIPITOUSLY QUENCHING THE DIHALOBORANE-CONTAINING STREAM TO MINIMIZE LOSS OF BORON-HYDROGEN BONDING.
