摘要
Fresh precipitates of amorphous TiO2 were used as the precursor to prepare brookite phase titania powders by hydrothermal method. The powders were characterized by XRD, Raman and TEM. All the results showed that the synthesized titania powders contained only brookite with a high purity of phase and uniform crystal size. The transformation from brookite to rutile occured when the powders were calcined at 900 degreesC and was completed at 1 000 degreesC.
