B14Li3

B14Li3 is an experimental boron-lithium ceramic compound that belongs to the family of lightweight refractory ceramics with potential high-temperature and structural applications. This material is primarily of research interest for advanced aerospace and energy applications where extreme thermal stability and low density are critical, though it remains largely in development phases outside specialized laboratory settings. Its appeal lies in the possibility of combining boron's refractory properties with lithium's low atomic mass to create materials suitable for demanding thermal or structural environments where conventional ceramics may fall short.
