· JVASP-18385· DyH2

DyH2 is a dysprosium hydride ceramic compound belonging to the rare-earth hydride family, formed through the incorporation of hydrogen into dysprosium metal lattices. This material is primarily of research and developmental interest, studied for applications requiring high-temperature stability, neutron absorption, and specialized electronic or thermal properties inherent to rare-earth systems. Its use remains largely confined to advanced materials research, nuclear engineering contexts, and specialized applications where dysprosium's unique nuclear and magnetic properties combined with hydride chemistry offer performance advantages over conventional ceramics.
