· JVASP-38594· NdH3

Neodymium trihydride (NdH₃) is an ionic ceramic compound formed through hydrogenation of rare-earth neodymium metal, belonging to the rare-earth hydride family. While primarily of research and industrial chemistry interest rather than mainstream structural engineering, NdH₃ serves niche applications in hydrogen storage research, catalysis, and specialty metallurgical processing where controlled hydride formation and decomposition are exploited. Its appeal lies in the rare-earth hydride system's ability to reversibly absorb and release hydrogen under specific thermal and pressure conditions, making it relevant to emerging clean energy technologies and advanced materials synthesis.
