Er3H
ceramic· JVASP-123205· 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.

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.
