· JVASP-99790· HoErMg2

HoErMg₂ is a rare-earth magnesium intermetallic ceramic compound containing holmium and erbium as primary alloying elements. This material represents an experimental composition within the rare-earth magnesium family, investigated primarily for high-temperature structural applications and potentially for functional properties exploiting rare-earth magnetic or optical characteristics. The specific combination of heavy rare earths (Ho, Er) with magnesium is relatively uncommon and suggests research focus on enhancing thermal stability, oxidation resistance, or specialized physical properties beyond conventional Mg alloys.

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.
