Barium chromate Chemical Properties,Usage,Production

Chemical Properties

heavy, yellow powder(s); rhomb, monoclinic; prepared from BaCl2 and Na2CrO4solutions, followed by filtering resulting precipitate; used in safety matches, as a corrosion inhibitor [MER06] [HAW93]

Physical properties

Yellow orthorhombic crystal; density 4.50 g/cm3; darkens on heating; insoluble in water and organic solvents; dissolves in mineral acid with decomposition.

Uses

Barium chromate is a pigment almost entirely in anticorrosion jointing pastes to prevent electro-chemical corrosion at junctions of dissimilar metals; some use in artists' colors and in coloring glass, ceramics, porcelain. Also used in metal primers, pyrotechnic compositions.

Hazard

Confirmed carcinogen.

Safety Profile

Confirmed human carcinogen. A poison. Mutation data reported. Reacts vigorously with reducing materials. See also BARIUM COMPOUNDS (soluble) and CHROMIUM COMPOUNDS. Used in pyrotechnics and as an explosive initiator.
