· JVASP-8110· Tb2Fe2Si2C

Tb2Fe2Si2C is a ternary intermetallic compound combining terbium (a rare-earth element), iron, silicon, and carbon. This material belongs to the family of rare-earth transition metal carbides and silicides, which are primarily investigated in research settings for their potential in high-performance applications requiring enhanced mechanical strength and thermal stability. While not yet widely commercialized, materials in this class are explored for applications demanding resistance to extreme conditions, such as aerospace thermal barriers, high-temperature structural components, and advanced magnetic or electronic devices leveraging rare-earth properties.
