| Calcium chromate Usage And Synthesis |
| Chemical Properties | Calcium chromate is a yellow crystalline
solid, often used in solution. Odorless. It normally occurs
as the dehydrate and loses water @ 200C. | | Uses | As a pigment, corrosion inhibitor; manufacture of chromium; in oxidizing reactions; in battery depolarization. | | Uses | Calcium 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 Description | CALCIUM 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 Reactions | Insoluble in water. | | Reactivity Profile | CALCIUM CHROMATE is a strong oxidizer and reacts with acids and ethanol. | | Hazard | Probable carcinogen. | | Health Hazard | Inhalation 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 Profile | Suspected 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 Exposure | Calcium chromate is used as a pigment, corrosion inhibitor; in the manufacture of chromium;
in oxidizing reactions; in battery depolarization. | | Shipping | UN3288 Toxic solids, inorganic, n.o.s., Hazard
Class: 6.1; Labels: 6.1-Poisonous materials, Technical
Name Required | | Incompatibilities | A strong oxidizer. Incompatible with
boron (violent reaction), ethanol, combustibles, organic, or
other easily oxidized materials. | | Waste Disposal | Reduce to trivalent chromium
and precipitate as chromium(III) hydroxide. Compact the
sludge and dispose in single purpose special waste
dumps |
