Calcium chromate Usage And Synthesis
Chemical PropertiesCalcium chromate is a yellow crystalline solid, often used in solution. Odorless. It normally occurs as the dehydrate and loses water @ 200C.
UsesAs a pigment, corrosion inhibitor; manufacture of chromium; in oxidizing reactions; in battery depolarization.
UsesCalcium chromate is used as a corrosion inhibitor and pigment. It is also used as a depolarizer in batteries and a metal coating and primer. Further, it is used in electroplating, photochemical processing and industrial waste treatment.
General DescriptionCALCIUM CHROMATE is a yellow powder. CALCIUM CHROMATE is slightly soluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to prevent its spread to the environment.
Air & Water ReactionsInsoluble in water.
Reactivity ProfileCALCIUM CHROMATE is a strong oxidizer and reacts with acids and ethanol.
HazardProbable carcinogen.
Health HazardInhalation causes irritation of nose and throat. Ingestion causes severe circulatory collapse and chronic nephritis. Contact with eyes causes irritation. Contact with skin may cause dermatitis and ulcers.
Safety ProfileSuspected human carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Experimental reproductive effects. Mutation data reported. A powerful oxiduer. Mixture with boron burns violently if ignited. See also CHROMIUM COMPOUNDS and CALCIUM COMPOUNDS.
Potential ExposureCalcium chromate is used as a pigment, corrosion inhibitor; in the manufacture of chromium; in oxidizing reactions; in battery depolarization.
ShippingUN3288 Toxic solids, inorganic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required
IncompatibilitiesA strong oxidizer. Incompatible with boron (violent reaction), ethanol, combustibles, organic, or other easily oxidized materials.
Waste DisposalReduce to trivalent chromium and precipitate as chromium(III) hydroxide. Compact the sludge and dispose in single purpose special waste dumps
