Abstract
By two-stage solid phase reaction, a series of Mg2Si 1-xGex continuous solid solutions were successfully synthesized at low temperature (823 K) for the first time. The product was single-phased without any oxide or carbide and the particle size was substantially reduced than that of the raw powders. X-ray diffraction techniques were used to explore the products´ phases and DTA to the changing tendency of heat quantity during the solid phase reaction. The influence of Ge substitution to Mg2Si1-x Gex was illustrated by the changes of lattice parameter and the existence of the complete solid solubility between Mg2Si and Mg2Ge was established, too
