Barium ferrate is the chemical compound of formula BaFeO4. This compound contains iron in the +6 oxidation state.[1] It is isostructural with BaSO4, and contains the tetrahedral [FeO4]2− anion.[2]

Preparation and chemistry[edit]

Anhydrous barium ferrate can be prepared by precipitation from a solution containing potassium ferrate and barium chloride.[3] Barium ferrate is an oxidising agent and has been proposed as an oxidising reagent for use in organic syntheses.[4]
