[edit] Properties
Calcium chromate is a bright yellow powder. It normally occurs as a dihydrate. When the hydrate is heated, it will lose water at 200C. Calcium chromate reacts with organic matter or reducing agents to form chromium(III). Calcium chromate will react explosively with hydrazine. If mixed with boron and ignited, calcium chromate will burn violently.[1]
[edit] Uses
It is used as a pigment, a corrosion inhibitor, and in electroplating, photochemical processing, and industrial waste treatment.
[edit] Health
Calcium chromate is a skin and eye irritant; it can also affect the respiratory tract, immune system, liver, and kidneys; calcium chromate is considered a human carcinogen.
