This letter describes the synthesis of CaAl 12O 19 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 CaAl 12O 19 powders have been obtained at 1200 °C for 2 h. The SEM examination shows that the hexagonal CaAl 12O 19 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 AlO 6 octohedra and AlO 4 tetrahedra in CaAl 12O 19.
