dc.description.abstractSb-doped magnesium silicide compounds have been prepared through ball milling and solid-state reaction. Materials produced were near-stoichiometric. The structural modifications have been studied with powder x-ray diffraction. Highly dense pellets of Mg2Si1-x Sbx (0 ≤ x ≤ 0.04) were fabricated via hot pressing and studied in terms of Seebeck coefficient, electrical and thermal conductivity and free carrier concentration as a function of Sb concentration. Their thermoelectric performance in the high temperature range is presented and the maximum value of the dimensionless figure of merit was found to be 0.46 at 810 K, for the Mg2Si 0.915Sb0.015 member. © 2013 TMS.en
