· JVASP-36033· ErH

Erbium hydride (ErH) is an intermetallic ceramic compound combining the rare-earth element erbium with hydrogen, belonging to the family of rare-earth hydrides. This material is primarily of research and specialized industrial interest, used in applications requiring high-temperature stability, neutron absorption, or unique optical/magnetic properties characteristic of erbium-based systems. ErH and related rare-earth hydrides are explored for nuclear shielding, hydrogen storage research, and as precursors for advanced ceramic and metallic materials synthesis, though commercial deployment remains limited compared to conventional structural ceramics.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
