EUClass = not listedZinc molybdate (ZnMoO4) is an
inorganic chemical compound . It is a whitepigment , which can be used ascorrosion inhibitor . While highly solublemolybdate s 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 andzinc chloride : the insoluble zinc molybdate will crystallize from this mixture.References
