IrO3
ceramic· JVASP-35217· IrO3
IrO₃ is an iridium oxide ceramic compound that belongs to the family of precious metal oxides, characterized by high chemical stability and catalytic properties. While primarily of research interest rather than established commercial production, iridium oxides are investigated for electrochemical applications, including oxygen evolution catalysis and electrodes in corrosive or high-temperature environments where conventional materials degrade. Engineers consider iridium oxides when extreme corrosion resistance, catalytic activity, or operation in harsh electrochemical conditions outweigh the cost premium of iridium-based materials.

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.
