· JVASP-16323· Sm3SnC

Sm₃SnC is a ternary ceramic compound belonging to the MAX phase family (metals, A-group elements, and C/N), specifically a samarium-tin carbide. This material represents a research-phase compound combining rare-earth elements with transition metals in a layered crystal structure that imparts both ceramic strength and metallic properties. While not yet widely commercialized, Sm₃SnC and related MAX phases are investigated for high-temperature structural applications, thermal management, and oxidation-resistant coatings due to their ability to maintain strength at elevated temperatures while offering damage tolerance superior to conventional monolithic ceramics.
