α-Zr(HPO4)2•H2O can be synthesized by hydrothermal method with thermal stability below temperature 460℃. The organic dispersants of n-propylamine and styrenated acrylic polymer have both effects of dispersion and intercalation on hydrothermal synthesized α-Zr(HPO4)2•H2O. The acidified zirconium phosphate can be intercalated effectively by the functional groups of CH2=CH-CH2~and~NH belonged to silane species.
