· JVASP-62082· Ca5Au3

Ca5Au3 is an intermetallic compound combining calcium and gold, belonging to the rare-earth and precious-metal intermetallic family. This is a research-stage material rather than an established engineering alloy; intermetallics of this type are primarily studied for fundamental materials science to understand phase stability, crystal structure, and potential electrochemical properties at the intersection of reactive (calcium) and noble (gold) elements. Beyond academic interest, such compounds may eventually find niches in specialized applications requiring unique electronic or catalytic behavior, though practical engineering use remains limited and material processing presents significant challenges due to calcium's high reactivity and gold's cost.

Export Control

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.
