Zinc molybdate (ZnMoO4) is an inorganic chemical compound. It is a white pigment, which can be used as corrosion inhibitor. While highly soluble molybdates like e.g. sodium molybdate are toxic in higher doses, zinc molybdate is essentially non-toxic because of its insolubility in water. Molybdates possess a lower toxicity than chromates or lead salts and are therefore seen as an interesting alternative to these salts for corrosion inhibition. It can be synthesized by mixing aqueous solutions of sodium molybdate and zinc chloride: the insoluble zinc molybdate will crystallize from this mixture.
