ceramic

· Sr2H5Rh

Sr2H5Rh is an experimental ceramic hydride compound containing strontium, hydrogen, and rhodium. This material belongs to the family of metal hydride ceramics, which are primarily of research interest for hydrogen storage, catalytic, and solid-state chemistry applications. Sr2H5Rh and related strontium-rhodium hydrides are not currently established in mainstream industrial production, but represent an emerging area of materials science focused on understanding how hydrogen incorporation into complex ceramic matrices affects structural and functional properties.
