K4IrO4
ceramic· JVASP-2817· K4IrO4
K₄IrO₄ is an iridium-potassium oxide ceramic compound belonging to the family of mixed-metal oxides. This is a research and specialized material rather than a commodity ceramic, of interest primarily in electrochemistry and catalysis due to iridium's noble-metal stability and catalytic activity in oxidizing environments. The potassium incorporation modifies the crystal structure and surface properties, making it potentially valuable for oxygen evolution reactions, sensor applications, and other electrocatalytic processes where corrosion resistance and catalytic selectivity are critical.

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.
