Abstract
875,898. Obtaining purified arsenic. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 28, 1960 [April 13, 1959], No. 12465/59. Class 82(1) Pure arsenic is obtained by moving a heater 2 progressively along an elongated reaction chamber 1 containing an oxide of arsenic and simultaneously passing a reducing gas, e.g. hydrogen, through in the opposite direction. The reduced arsenic voltalizes and is condensed in the part C of the chamber remote from the heater in the direction of the gas flow. The direction of movement of the heater and of the gas may be periodically reversed to cause further purification of the arsenic. Arsenic contaminated with sulphur may be substituted for the oxide and the arsenic may be formed in situ by thermal decomposition of arsenous hydride. Elements to be alloyed with the pure arsenic, e.g. aluminium, gallium and indium, are placed at D and the heater and gas both moved in this direction; the zone D is then sealed and the constituents alloyed by passing the heater repeatedly in both directions along the sealed tube.
