• Inhalation Risk: A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.
• Effects of Short Term Exposure: The substance is irritating to the eyes, skin and respiratory tract.
• Effects of Long Term Exposure: Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma. Repeated or prolonged inhalation may cause nasal ulceration. This may result in perforation of the nasal septum. The substance may have effects on the kidneys. This may result in kidney impairment. This substance is carcinogenic to humans.
• 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 has been found to be useful in many capacities. often the compound is used as a carrier for the chromium ions. is an oxidizing agent, making it useful as a burn rate modifier in pyrotechnic compositions. It is especially useful in delay compositions such as delay fuses. It is also used in the composition of a catalyst for alkane dehydration. 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.
