Barium ferrate hydrochloric acid, releasing chlorine. The irreversible reaction of digesting barium chromate with a solution of sodium ferrate forms barium ferrate, and the color of the solution is changed from red to yellow due to the sodium chromate that is also formed. Alkaline sulfates decompose barium ferrate that has not been dried, forming barium sulfate, ferric hydroxide and oxygen gas. Barium ferrate, therefore, appears to be one of the most insoluble salts known. Barium ferrate Barium ferrate is the chemical compound of formula BaFeO. This is a rare compound containing iron in the +6 oxidation state. The ferrate(VI) ion has two
Metallic fiber Metallic fiber Metallic fibers are manufactured fibers composed of metal, plastic-coated metal, metal-coated plastic, or a core completely covered by metal. Gold and silver have been used since ancient times as yarns for fabric decoration. More recently, aluminum yarns, aluminized plastic yarns, and aluminized nylon yarns have replaced gold and silver. Metallic filaments can be coated with transparent films to minimize tarnishing. Metal fiber may also be shaved from wire (steel wool), bundle drawn from larger diameter wire, cast from molten metal, or grown around a seed (often carbon).
