· JVASP-112293· B2OsW2

B2OsW2 is a refractory metal compound combining osmium and tungsten with boron, belonging to the family of ultra-high-melting-point intermetallic and ceramic-metal composites. This material exists primarily in research and development contexts, explored for extreme-temperature applications where conventional superalloys reach their limits. Its notable characteristics derive from the exceptional thermal stability and hardness of both constituent elements, making it of interest for specialized aerospace and high-energy applications.
