|Section2= |Section3= |Section7= |Section8= }} Zinc chromate, ZnCrO4, is a chemical compound containing the chromate anion, appearing as odorless yellow powder or yellow-green crystals, but when it is used for coatings pigments are often added. It is used industrially in chromate conversion coatings, having been developed by Ford Motor Company in the 1920s. ==Production== A process known as the Cronak process is used to create zinc chromate for use in industry. This process is done by putting zinc or a zinc plated metal in a solution of sodium dichromate and sulfuric acid for a few seconds. Zinc chromate can also be synthesized by using neutral potassium chromate (K2CrO4) and zinc sulfate (ZnSO4), which forms a precipitate. K2CrO4 + ZnSO4 → ZnCrO4 + K2SO4 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「zinc chromate」の詳細全文を読む スポンサード リンク
