· Ca1 Ge2 Ru2

Ca₁Ge₂Ru₂ is an intermetallic semiconductor compound combining calcium, germanium, and ruthenium in a fixed stoichiometric ratio. This is a research-phase material rather than a commercial product, belonging to the broader family of ternary intermetallic semiconductors that are being explored for their electronic and thermoelectric properties. The material's potential lies in niche applications where the electronic structure afforded by this specific metal combination—particularly ruthenium's d-band contributions and germanium's semiconducting character—could enable novel device performance not achievable with conventional binary semiconductors.

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.
