Er3H

Er3H is a rare-earth hydride ceramic compound based on erbium, belonging to the family of lanthanide hydrides that exhibit unique combinations of ionic and metallic bonding character. These materials are primarily investigated in research contexts for their potential in neutron absorption, nuclear shielding, and specialized high-temperature applications where rare-earth chemistry offers advantages over conventional ceramics. Er3H and related hydride systems remain largely in the experimental phase but are notable for their density and potential thermal stability, making them candidates for advanced nuclear and aerospace engineering where weight-critical neutron moderating or absorbing functions are required.
