[citation needed] It is an oxidiser, oxidising organic compounds (e.g. alcohols) or reducing agents (e.g. metals) to the corresponding carbonyl compounds or metal oxides while the chromium(VI) centre in CaCrO4 is reduced to chromium(III).

It will also burn violently if mixed with boron and ignited, thereby posing a fire hazard.

[2] The compound is occasionally used as a yellow inorganic pigment, or a corrosion inhibitor as part of the chromate conversion coating procedure.

[citation needed] It has been also utilised in chromium electroplating, in photochemical processing, and as an industrial waste treatment.

[citation needed] All applications suffer from the high toxicity of chromium(VI) species to humans, with chromates listed as IARC Group 1 carcinogens while also very corrosive (e.g. capable of producing permanent eye damage) and genotoxic.
