Abstract:
Objective To study the structural and anticorrosive property of microcrystalline α-Zn3 (PO4)2 ·4H2O. Methods Zinc phosphate was prepared from zinc acetate and orthophosphate acid in aqueous solution.Structural characteristics of products were investigated by XRD, RAMAN, FTIR, TG-DTA, SEM, surface area,particle size distribution, and density measurements. Results The title compound, a highly crystalline, micronized (A), c0 =5. 0304(A), V=975.86 (A)3. Its specific area is 0. 701 m2/g, density 3. 1612 g/m3 , and average size 4.75μm . Conclusion Comparing with commercial Zinc phosphate, the synthesized iamellar microcrystalline zinc phosphate had excellent anticorrosive property and dispersibility.
