· Ca1 Ge2 Au2

Ca₁Ge₂Au₂ is an intermetallic semiconductor compound combining calcium, germanium, and gold in a defined stoichiometric ratio. This is a research-phase material rather than an established commercial alloy; it belongs to the family of ternary intermetallics that are investigated for potential optoelectronic and thermoelectric applications. The incorporation of gold—a noble metal with high electron mobility—alongside germanium's semiconductor properties suggests interest in high-performance electronic or photonic device structures, though practical applications remain primarily in the laboratory stage.

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.
