New Synthesis Method of the Lamellar Zinc Phosphate and its Electrochemical Corrosion Inhibitions

Abstract:

A new synthesis method namely hydrolysis precipitation was used to prepare Zn₃(PO₄)₂•4H₂O. Structural characteristics of products were investigated by X-ray Diffraction, scanning electron microscope and chemical analysis. The electrochemical corrosion inhibitions of title zinc phosphate were studied by electrochemical impedance of coating immersion test. The results show that the obtained product is a highly crystalline, micronized and lamellar Zn₃(PO₄)₂•4H₂O. Comparing with commercial zinc phosphate, the synthesized lamellar microcrystalline product has excellent anticorrosive property and dispersibility.
