Barium ferrate purity of the synthesized barium ferrate by performing the reaction at low temperature in the absence of carbon dioxide and by rapidly filtering and drying the precipitate. Addition of a soluble sodium barium salt to an alkali metal ferrate solution produces a maroon precipitate of barium ferrate, a crystal which has the same structure as barium chromate and has approximately the same solubility. The wet method employs chemical and electrochemical techniques. Barium ferrate, BaFeO can be prepared by adding barium oxide to a mixture NaClO and ferric nitrate at room temperature (29± 1 °C). The precipitate formed can then be
