Lithium hydride (Li₃H) is an ionic ceramic compound combining lithium metal with hydrogen, representing a materials chemistry boundary between metallic and ceramic behavior. This compound exists primarily in research and specialized aerospace contexts rather than widespread commercial use, valued for its extremely low density and potential as a solid-state hydrogen storage or neutron shielding medium in advanced nuclear applications.
