| Hazard Information | Back Directory | [Hazard]
Confirmed carcinogen. | [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. | [Application]
Barium chromate is an oxidizing chemical compound composed of the elements barium and chromium. It 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. | [Uses]

| [Preparation]
Interaction of barium chloride and sodium chromate. The precipitate is washed, filtered and dried.
