· KAuI4O12

KAuI4O12 is an iodide-based mixed-metal oxide semiconductor containing potassium, gold, and iodine in a complex ternary structure. This is a research-phase compound rather than an established commercial material; it belongs to the family of halide perovskites and mixed-metal oxides being investigated for optoelectronic and photovoltaic applications where unconventional band structures and tunable electronic properties are sought. The presence of gold as a dopant or structural element is of particular interest for applications requiring enhanced optical absorption or plasmonic effects, though practical engineering use remains largely confined to materials research laboratories.

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.
