Zinc chromate has been primarily used in the formulation of anti-corrosion primers and paints, especially for metal surfaces in the aerospace and automotive industries. It serves as a reference compound in research related to corrosion resistance and is also utilized in the production of other chromium compounds. Additionally, it has applications in the manufacturing of glass and ceramics, where its pigmenting properties are advantageous. Despite its historical significance, the use of zinc chromate is now limited due to health and environmental concerns, leading to the development of safer alternatives.
