· Ba6 Ni2 Ir4 O18

Ba₆Ni₂Ir₄O₁₈ is a complex mixed-metal oxide ceramic containing barium, nickel, and iridium in a structured lattice—a compound primarily of research interest rather than established commercial production. This material belongs to the family of multivalent transition-metal oxides, which are investigated for electrochemical catalysis, solid-state ionics, and high-temperature ceramic applications due to the synergistic properties enabled by combining noble-metal (Ir) and base-metal (Ni) sites. While not yet widely deployed in production, materials of this composition class are promising candidates for oxygen evolution catalysis in water-splitting systems, solid oxide fuel cell components, and corrosion-resistant coatings where iridium's nobility and nickel's electrochemical activity provide complementary advantages.

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.
