We have investigated the contact fusion in a binary system with a complex state diagram for different techniques of heating the contact of massive antimony and tellurium specimens with the use of the autothermal e.m.f. method. A decrease in the contact fusion temperature compared to the fusion temperature of the metastable eutectic due to the action of metastable processes has been revealed by experiment. We have established the formation of a metastable Sb + Te eutectic by X-ray structural, X-ray microspectrum, and microstructural analyses and by microhardness measurements of contact interlayers as well as by secondary fusion. Theoretical calculations of the heat released as a result of the exothermal reaction of intermediate Sb2Te3 phase formation have been performed.
