  • Intermetallic compounds and metal purification
    Patent number: 4082547
    Abstract: By thoroughly mixing a compound of a base metal with a metal of the eighth subgroup of the Periodic Table, heating the resultant to a temperature in excess of 800.degree. C at which it is subjected to a stream of hydrogen and treating thus-obtained intermetallic compound at a still higher temperature and under a high vacuum, a base metal having a purity of at least 98 percent results. When the base metal is an actinide, an alloy or a mixture of alloy and intermetallic compound may be obtained in lieu of the indicated intermetallic compound.
    Type: Grant
    Filed: May 30, 1974
    Date of Patent: April 4, 1978
    Assignee: Gesellschaft fur Kernforschung m.b.H.
