Crystalline samples of α-zirconium hydrophosphate (abbreviated as α-ZrP) were prepared by hydrothermal method and characterized by XRD, IR, TEM and TG-DSC. There are highly crystalline with an interlayer distance of 7.63A and hexagonal flakes in α-ZrP. Meanwhile, it is shown that α-ZrP possesses a high thermal stability. The optimum experimental condition for hydrothermal method is at 180℃in 5M ～ 10M phosphoric acid beyond 48 hours.
