Zinc molybdate is an inorganic compound with the formula ZnMoO4. It is used as a white pigment, which that is also a corrosion inhibitor. A related pigment is sodium zinc molybdate, Na2Zn(MoO4)2.[4] The material has also been investigated as an electrode material.[5]
In terms of its structure, the Mo(VI) centers are tetrahedral and the Zn(II) centers are octahedral.[2]
Safetyedit
The LD50 (oral, rats) is 11,500 mg/kg.[4] While highly solublemolybdates 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 alternative to these salts for corrosion inhibition.
