TbNiSb
metal· TbNiSb
TbNiSb is an intermetallic compound composed of terbium, nickel, and antimony, belonging to the class of rare-earth-based metallic materials. This compound is primarily of research interest for its potential in thermoelectric and magnetic applications, where rare-earth intermetallics can offer tailored electronic and thermal properties. While not yet widely deployed in mainstream engineering, materials in this family are being investigated for energy conversion devices and advanced functional applications where the combination of rare-earth elements with transition metals enables control over carrier concentration and phonon scattering.
