· Sm1 B12

Sm1B12 is a rare-earth boride ceramic compound combining samarium with boron in a dodecaboride crystal structure, representing a member of the hexaboride and higher boride family of materials. This material is primarily investigated in research contexts for its potential in high-temperature applications and thermionic emission devices, where rare-earth borides offer advantages in electron emission at elevated temperatures. Compared to conventional refractory ceramics, rare-earth borides provide improved electrical conductivity and lower work functions, making them candidates for specialized thermal and electronic applications, though industrial adoption remains limited outside niche research and aerospace development.
