Zinc chromate, ZnCrO4, is a chemical compound, a salt containing the chromate anion, appearing as odorless yellow powder or yellow-green crystals, but, when used for coatings, pigments are often added.[2][3][4] It is used industrially in chromate conversion coatings, having been developed by the Ford Motor Company in the 1920s.[5]
