· Te18 Ta9

Te18 Ta9 is a tellurium-tantalum compound semiconductor, likely an intermetallic or mixed-valence phase combining tellurium's semiconducting properties with tantalum's refractory characteristics. This appears to be a research or specialized material rather than a widely commercialized alloy; such tellurium-based compounds are investigated for thermoelectric conversion, high-temperature electronics, and niche optoelectronic applications where the combined properties of both elements offer advantages over 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.
