Abstract

Crystalline powders of Re and Si in the composition ratio varing from Re:Si=1:4 to 2:1 were mechanically alloyed by a laboratory ball mill in an inert atmosphere. In the course of the mechanical alloying reaction, the halo patterns which are characterized as the amorhous alloy powders was not obtained, but the formation of rhenium silicides(ReSi₂ and Re₅Si₃) have been recognized, judging from the measurement of XRD. Moreover, from the electrical conductivity measurement of the rhenium silicide pellets, it was found that the semiconductive phenomena were clearly exhibited in the range from room temperature to about 473K and the activation energies were 1.23eV for Re₅Si₃ and 0.27 eV for ReSi₂, respectively.
