Fabrication of large sintered pellets of Sb-doped n-type Mg2Si using a plasma activated sintering method

► We have developed a metallic binder for the Sb-doped Mg2Si sintering process. ► Sb-doped Mg2Si pellets up to 30 mm in diameter with no internal cracks. ► Incorporation of 5 wt% Ni binder affected an increase in the ZT value up to 0.97.
