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]
