Zirconium phosphate( α-Zr P) was prepared by the hydrothermal method of directly one- step using Zr OCl2·8H2O and phosphoric acid as raw materials. FT-IR,SEM and XRD were used to characterize the product. The influence of the concentration( 3 mol·L- 1and 6 mol·L- 1)for phosphoric acid on the yield,crystallization,size and distribution of α-Zr P were studied. The results show that α-Zr P with layer structure and high crystallization have been successfully synthesized. The α-Zr P- 6M with size of 500 nm prepa...
