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
Metallic dragon Metallic dragon Metallic dragon is a classification of dragon found in the role playing game "Dungeons & Dragons". In this setting metallic dragons are of good alignment. Bahamut is the deity of good-aligned dragons and metallic dragons, and currently the only known Platinum dragon in existence. Metallic dragons have played a large role in D&D's various monster compilation books, and for most of the game's history five main types - brass, copper, bronze, silver, and gold - were presented as roughly analogous to the five types of chromatic dragons. The fourth edition of the game's second "Monster Manual" substituted iron
