Particle size of zinc phosphate was controlled-synthetized by grinding reaction instead of stirring reaction and assisted surfactant in the solid-liquid reaction system between zinc oxide and phosphoric acid.The effects of grinding medium,grinding ball ratio,ball-to-material ratio,solid-liquid ratio and surfactant on the particle size distribution,morphology and agglomeration of zinc phosphate were investigated.Nano zinc phosphate was characterized by SEM,XRD,particle size distribution and TEM.Results showed that the non-aggregation granular nanometer zinc phosphate with particle size distribution between 59~79 nm and average particle size of 68 nm could be prepared under the technological conditions as follows:c(CTAB)=9×10-4mol/L,grinding time was 3 h,zirconium ball as grinding medium,mass ratio of ball to material was 150:1,grinding ball mass ratio of Φ10 mm and Φ6 mm was 1:4,rotating speed was 200 r/min and solid-liquid ratio[mass ratio of zinc oxide to(phosphoric acid+surfactant)] was 1:1.
