· JVASP-37261· SmRe3

SmRe3 is an intermetallic ceramic compound combining samarium (rare earth element) and rhenium, representing a high-density material system studied for extreme-environment applications. This compound belongs to the family of rare-earth–refractory metal ceramics, which are primarily explored in research and aerospace contexts rather than established commercial production. SmRe3 is investigated for potential use in ultra-high-temperature structural applications, wear-resistant coatings, and advanced thermal management systems where conventional ceramics or superalloys reach performance limits.
