| | Calcium chromate Usage And Synthesis |
| Description | Calcium chromate is a yellow crystalline solid,often used in solution. Odorless. It normally occurs as thedehydrate and loses water at 200℃. Molecularweight=192.1. Hazard Identification (based on NFPA-704M Rating System): Health 2, Flammability 0, Reactivity 0.Insoluble in water. | | 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. | | First aid | If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least30 min, occasionally lifting upper and lower lids. Seekmedical attention immediately. If this chemical contactsthe skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove fromexposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing hasstopped and CPR if heart action has stopped. Transferpromptly to a medical facility. When this chemical hasbeen swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. | | storage | Color Code—Blue (carcinogen): Health Hazard:Store in a secure poison location. Calcium chromate mustbe stored to avoid contact with combustible, organic, orother easily oxidized materials (such as paper, wood, sulfur,aluminum, hydrazine and plastics) since violent reactionsoccur. A regulated, marked area should be established where this chemical is handled, used, or stored in compliance with OSHA Standard 1910.1045. | | 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 |
