· Ho8 Au4

Ho8Au4 is an intermetallic compound combining holmium (a rare-earth element) with gold, forming a definite stoichiometric phase rather than a solid solution alloy. This material belongs to the family of rare-earth–noble-metal intermetallics, which are primarily of research interest for their unique electronic, magnetic, and thermal properties; it is not a commodity engineering material in widespread industrial use.

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.
