· JVASP-64612· Ba4SrRu

Ba₄SrRu is a complex oxide ceramic compound combining barium, strontium, and ruthenium elements, representative of the perovskite-related ceramic family. This material is primarily of research interest rather than established commercial use, being investigated for potential applications in electrochemistry and solid-state ionics where mixed-valence transition metals and alkaline earth dopants can enhance ionic or electronic conductivity. Compared to conventional oxide ceramics, barium-strontium ruthenates show promise in oxygen reduction catalysis and electrochemical device applications, though engineering adoption remains limited pending further characterization and scaling feasibility.

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.
