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]
