· K4 Se20 Au4

K4Se20Au4 is an experimental intermetallic compound combining potassium, selenium, and gold in a defined stoichiometric ratio, representing a research-phase material rather than an established engineering alloy. This material belongs to the family of complex chalcogenide-based intermetallics and is primarily of interest in materials science research for studying novel electronic, thermal, or structural properties arising from its multi-component composition. Potential applications remain largely exploratory, with relevance primarily in academic settings or specialized research environments rather than mainstream industrial manufacturing.

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.
