Simple Synthesis of Layered Zinc Phosphate and Its Evaluation of the Corrosive Effectiveness

摘要

A simple synthesis method namely solvent displacement crystallization was used to prepare zinc phosphate, and obtained product was characterized by X-ray diffraction, scanning electron microscope and chemical analysis. The corrosive effectiveness of title zinc phosphate was evaluated by electrochemical impedance of two coatings immersion test. The results show that the obtained product is a highly crystalline, micronized and layered zinc phosphate. Comparing with commercial zinc phosphate, the synthesized layered microcrystalline product has excellent anticorrosive property in alkyd or epoxy coatings.
