Alloys of the Bi-Sb system are used in instruments manufacturing due to their transport properties (electrical resistivity, Hall coefficient, differential thermo-emf, etc.). In this work, the results of an investigation of the thermal stability of the dendritic structure and the effect of homogenization on the transport properties of Bi alloys with 12 at.% Sb are presented. It is shown that the homogenization of bismuth alloys containing antimony leads to a considerable increase in the magnetoresistance, absolute values of the Hall effect and the differential thermo-emf, and the thermoelectric-power coefficient. The homogenization time depends exponentially on the annealing temperature and the activation energy of the process is equal to (1.0+/- 0.1) eV.
