· JVASP-100303· Sm2MgSi2

Sm₂MgSi₂ is an intermetallic ceramic compound combining samarium, magnesium, and silicon, belonging to the family of rare-earth silicates. This material is primarily investigated in research contexts for high-temperature structural applications and thermal management systems where its thermal stability and ceramic nature offer potential advantages over conventional metallic alloys. The samarium-bearing composition positions it as a candidate for aerospace and nuclear applications where oxidation resistance and thermal shock resistance are critical, though commercial deployment remains limited compared to more mature ceramic systems.
