Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

Barium ruthenate is an inorganic compound, with the chemical formula of BaRuO3. It can be obtained from the stoichiometric reaction of barium oxide and ruthenium(IV) oxide at temperatures below 1200 °C,[3] or from the thermal decomposition of Ba[Ru(NO)(NO2)4(OH)]·xH2O.[4] It reacts with ruthenium and ruthenium(IV) oxide at 1250 °C to obtain black needle-like crystal BaRu6O12.[5] Hydrogen or zirconium can reduce it when heated to produce metal ruthenium.[1]
