摘要：

Hematite particles with various shapes have been synthesized through a simple hydrothermal reaction. The particle shape and size can be controlled by adjusting pH value in the starting solution. The products were characterized by X-ray powder diffraction patterns (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), high resolution transmission electron microscope (HRTEM), FT-IR, TG-DTA and mass spectrometry of gas species during TC-DTA. The TEM and HRTEM results revealed that large numbers of micropores ranging from 0.5-0.6 turn existed in the surface of spherical particles. (C) 2009 The Ceramic Society of Japan.
