· JVASP-38405· PrH

PrH is a rare-earth hydride ceramic compound based on praseodymium, belonging to the family of lanthanide hydrides. These materials are primarily of research and specialized industrial interest, valued for their unique electronic and thermal properties that differ significantly from their parent rare-earth metals. PrH compounds are investigated for applications in hydrogen storage, neutron absorption, and specialized electronic devices where the hydride phase offers advantages over conventional ceramics or metallic alternatives.
