【Abstract】 Crystalline samples of α Titanium hydrophosphate (abbreviated as α TiP) were prepared by hydrothermal method and characterized by XRD, IR, HREM and TG DSC. There is a high crystallinity with an interlayer distance of 0 763 nm and hexagonal flakes in α TiP. Meanwhile, it is shown that the α TiP Possesses a high thermal stability.In this paper,the experimental conditions for preparing α Tip by hydrothermal synthesis were systematically investigated. The results indicate that the optimum experimental condition for hydrothermal method is at 180℃ for 6 hours in 5 M 10 M phosphoric acid concenfration.更多还原
