Abstract
Mg_2Si is one of the most promising functional magnesium compounds to be synthesized. Mg_2Si is expected to be thermoelectric material system working at relatively high temperature range. Although the conventional milling type mechanical alloying is frequently favored and used among researchers as laboratory-scaled processing, long processing time as well as contamination becomes something an issue of nuisance. The bulk mechanical alloying (BMA) provides us an alternative solid-state processing to synthesize and consolidate Mg_2Si with heat treatment. Within 20-150 cycles of BMA, this starting elemental granular mixture can be fully reacted into Mg_2Si after suitable heat treatment.
