Abstract: MoSi2 and MoSi2-based composites have always been paid much attention as important materials for heating and high temperature structural
applications, because of its high melting point(2303K), excellent elevated temperature oxidation resistance and good electrical resistivity. In this
paper, new developments in recent years from international and domestic materials science circles were reviewed in detail, and some impressive
aspects about MoSi2, including deformation mechanisms, oxidation mechanisms and composite strengthening and toughening, were also briefly
described and summarized. Finally, the present and potential applications of MoSi2 materials were appraised and prospected, it was suggested that
MoSi2 could be one of the most promising candidate materials for high-temperature structural applications in the 21-century.
