· JVASP-62415· CaB2H8

CaB2H8 (calcium borohydride) is an inorganic ceramic compound and complex metal hydride belonging to the borohydride family of materials. This is primarily a research-stage material investigated for hydrogen storage and energy applications rather than a conventional structural ceramic. The material is notable within the context of solid-state hydrogen storage systems, where borohydrides show promise for portable power generation and fuel cell applications due to their high theoretical hydrogen content, distinguishing them from traditional ceramic matrices used in thermal or mechanical applications.
