Description
Metal/semiconductor Mg$_2$Si compounds was synthesized by solid state reaction method. The sample was calcined at temperature 973 K in vacuum system. It was pressed into pellet, and then was sintered in hot-pressing process at 973 K. The Mg$_2$Si was studied structure properties by XRD and SEM, electrical properties by Hall Effect at room temperature and thermal properties by laser flash method at 300 up to 500 K. Finally, the results of normal process and hot-pressing process effect on thermal conductivity were compared and reported.
