· Co1 Re1 Ge2

Co1Re1Ge2 is an intermetallic compound combining cobalt, rhenium, and germanium in a 1:1:2 stoichiometric ratio. This is a research-phase material within the broader family of transition metal germanides, studied primarily for potential semiconductor and thermoelectric applications where the combination of refractory metals (Co, Re) with germanium offers tailored electronic and thermal properties. The material remains largely experimental, with development focused on understanding its phase stability and electronic behavior for next-generation device applications where conventional semiconductors reach performance limits.

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.
