· Ba2 Ru1 O4

Ba₂RuO₄ is a barium ruthenate ceramic compound belonging to the family of perovskite-derived oxides. This material is primarily of research interest as an advanced oxide semiconductor with potential applications in electrochemistry and solid-state electronics, rather than an established industrial material. The ruthenate family is notable for combining metallic conductivity with ceramic stability, making compounds like this candidates for emerging technologies in catalysis, solid oxide fuel cells, and novel electronic devices where conventional semiconductors are unsuitable.

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.
