The Mg_2Si/Mg composites, which show excellent mechanical properties, have been produced via solid-state synthesis in the previous study. In this report, the reaction behavior of Mg and Si was investigated to evaluate the effects of particle characteristics on the synthesis of Mg_2Si. Mg powder and two sizes of Si powders were employed as initial materials. They were mixed as Mg-5,10,20,30wt%Si and were cold pressed at 500 and 874 MPa. Powder mixtures with same composition were also prepared to compare with each compact. Those compacts and powder mixtures were analyzed by DTA. From a view point of the Mg_2Si formation in solid-state, the suitable temperature ranees of the reaction and its exothermic heat were discussed.
