| As has already been mentioned, tellurium combines with many metals giving compounds the existence of which has usually been demonstrated by investigation of the freezing-point curves of mixtures in varying proportions, making Alloys of Tellurium. In this way the combinations, TeCd (1041° C.), TeSn (780° C.), Te2Au, TeZn (1238° C.), TeHg, Te3As2, Te3Bi2, Te3Sb2, TeCu2, Te3Cu4, TeSn (769° C.), etc., have been detected, the bracketed figures giving the corresponding melting-points. The Alloys of Tellurium are of no practical importance except in so far as they occur in nature and serve as sources of the respective constituents. |
