Abstract EN
Mg2+xSi0.7Sn0.3Sbm (0≤x≤0.2, m=0 or 0.01) solid solutions have been successfully prepared by mechanical alloying and hot pressing as a solid-state synthesis route.
All specimens were identified as phases with antifluorite structure and showed n-type conduction.
The electrical conductivity of Mg-excess solid solutions was enhanced due to increased electron concentrations.
The absolute values of the Seebeck coefficient varied substantially with Sb doping and excess Mg, which was attributed to the change in carrier concentration.
The onset temperature of bipolar conduction was shifted higher with Sb doping and excess Mg.
The lowest thermal conductivity of 1.3 W/mK was obtained for Mg2Si0.7Sn0.3Sb0.01.
A maximum ZT of 0.64 was achieved at 723 K for Mg2.2Si0.7Sn0.3Sb0.01.
