Samarium boride (SmB₆) is a rare earth boride compound prized for its exceptional electronic, thermal, and mechanical properties, particularly its behavior as a topological insulator. It is primarily used in advanced materials research and electronics, including applications in quantum devices, spintronics, and high-performance sensors due to its unique conductivity and stability. Samarium boride is also explored for thermoelectric materials that convert heat to electricity, with potential in energy harvesting and waste heat recovery. Its high hardness and refractory characteristics make it suitable for ceramics in aerospace, defense, and high-temperature environments. Furthermore, ongoing research examines its role as a catalyst in specialized chemical reactions requiring efficiency and control.
