Objective: To prepare boehmite powders. Methods: Esterification reaction assisted hydrothermal method.Results: In this study,boehmite powders was synthesized and its morphology and crystal form were characterized by techniques of transmission electron microscopy(TEM),scanning electron microscope(SEM),X-ray diffraction(XRD),Fourier transform infrared spectrometry(FTIR) and thermogravimetic analysis(TGA). Conclusion: Compared with conventional hydrothermal method,preparation of boehmite powders by esterification reaction assisted hydrothermal method have distinct advantages,such as : low energy consumption,high production efficiency,homogeneous morphology of the products.
