摘要：

This letter describes the synthesis of CaAl12O19 powders using micro reactors made of Igepal CO520/water/cyclohexane microemulsions. Characterization of the powder was done by DTA-TGA, X-ray diffraction, Scanning electron microscopy, Fourier Transform Infrared Spectroscopy. The XRD results show that the hexagonal CaAl12O19 powders have been obtained at 1200 degrees C for 2 h. The SEM examination shows that the hexagonal CaAl12O19 has plate-like grain morphology with most of the grain took the form of hexagonal platelets with-developed faces. The FTIR spectra show the lower frequency bands are assigned to AlO6 octohedra and AlO4 tetrahedra in CaAl12O19. (C) 2009 Elsevier B.V. All rights reserved.
