Abstract

The formation of highTc Nb3Al, Nb3Ga, Nb3Ge and V3 (Ga, Si) has been attempted by solid state diffusion from ternary bronzes. None of the desired compounds were formed. The results are explained in terms of the thermodynamics of compound formation by solid state diffusion. Diffusion follows two-phase tie-lines; only those phases which lie on tie-line routes, and which are the most stable as defined by the stability index, are able to form. The addition of the third element to the bronze in general has little significant effect. There is no evidence to indicate that highTc Nb3Al, Nb3Ga or Nb3Ge can be produced by solid state reaction.
