ceramic

· KAuO2

KAuO₂ is a ceramic compound containing potassium, gold, and oxygen, representing an uncommon mixed-metal oxide in the gold chemistry family. This material is primarily of research and academic interest rather than established industrial production, with potential applications in catalysis, electrochemistry, and advanced materials science where gold's unique chemical properties can be leveraged in ceramic form. Engineers would consider this material for experimental work in heterogeneous catalysis or functional ceramics where gold's catalytic activity combined with ceramic stability offers advantages over conventional gold or other precious metal systems.

Regulatory Screening

Environmental

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.
