· Ca1 Ge2 Ir2

Ca₁Ge₂Ir₂ is an intermetallic semiconductor compound combining calcium, germanium, and iridium in a defined stoichiometric ratio. This is a research-stage material rather than an established industrial compound; it belongs to the family of ternary intermetallics that show promise for thermoelectric and electronic applications due to the combination of a semiconducting germanium backbone with the high-density, high-stability iridium component. The calcium addition modulates the electronic structure and band gap, making this composition of interest to materials researchers exploring new thermoelectric generators, radiation detectors, or high-temperature semiconductor devices where conventional III-V or II-VI semiconductors face limitations.

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.
