FeSb

FeSb is an intermetallic compound consisting of iron and antimony that forms a metallic phase with relatively high density and moderate elastic stiffness. This material belongs to the class of binary metal-antimony compounds, which are primarily of research and specialized industrial interest rather than commodity materials. FeSb appears in thermoelectric applications, magnetic material studies, and semiconductor research contexts, where the combination of metallic conduction and antimony's properties can be exploited; it may also have potential in advanced catalysis or high-temperature alloy development, though large-scale industrial deployment remains limited compared to conventional iron alloys or purpose-designed thermoelectric materials.
