Preparation and Characterization of Anisotropic Ammonium Titanium Phosphate Crystals via Hydrothermal Route

Abstract:

Article Preview

A series of ammonium titanium phosphate nanocrystals were prepared by hydrothermal synthesis method, and characterized by XRD, IR, XPS, SEM and DTA/TG. The results showed that themicrostructures of the materials could be rod- or sphere-like nanocrystals with aqueous pH values changing from 0 to 5, and could be flake like nanocrystals when a certainty of oxalic acid was added to the hydrothermal systems. The hydrothermal duration and temperature were not the main factors influencing the morphology of the products, but longer time and higher temperature would make the material more highly crystalline. The hydrothermal synthesizing mechanism on different experimental conditions was also discussed.
