SmAl7Au3
metal· JVASP-22761· SmAl7Au3
SmAl7Au3 is an intermetallic compound combining samarium (a rare earth element), aluminum, and gold in a fixed stoichiometric ratio. This is a research-phase material studied primarily for its potential in high-temperature applications and specialized electronic or photonic devices where rare earth metallics offer unique magnetic, catalytic, or electronic properties. While not yet established in mainstream industrial production, materials in the samarium-aluminum-gold family are of interest in advanced materials chemistry for exploring novel phase diagrams, thermal stability, and functional properties that differ significantly from conventional engineering alloys.
