Description
Magnesium silicide (Mg${}_2$Si) is a promising for thermoelectric materials due to display a high performance for thermoelectric power generation with ZT about 0.9 at operation temperature 600 to 800 K. This work, Mg${}_2$Si compound was prepared from starting powder of SiO${}_2$, which was attracted from rice husk, and Mg powder. The sintering process was performed in quartz tube vacuum at temperature 650 ${}^{\circ}$C with argon atmosphere. Then MgO composition was demolished by chemical process. XRD patterns showed the pure phased of Mg${}_2$Si. Thermoelectric characterization and properties will be reported.
