· Ba1 Os1 O3

BaOsO₃ is a mixed-valence barium osmium oxide ceramic compound belonging to the perovskite family of functional oxides. This is a research material of interest in solid-state chemistry rather than an established commercial product; it exhibits properties relevant to catalysis and electrochemistry due to osmium's high oxidation state and the perovskite structure's ability to support oxygen-deficiency and mixed-valence states. The material is primarily explored for electrocatalytic applications where osmium-based oxides can serve as robust, corrosion-resistant active sites in oxygen-evolution and oxygen-reduction reactions under harsh conditions.

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.
