The cordierite powders were successfully synthesized by a solid state reaction method, by using raw materials of high purity powder of MgO, Al_2O_3 and SiO_2, mixed according to the stoichiometric ratio of cordierite. The cordierite powders were prepared under different manufacturing conditions and the phase structures were characterized by X-ray diffraction. The results showed the optimizing high purity and better flowability cordierite ceramic powder was achieved by using smaller size oxides particles at calcining temperature of 1425°C for 2 hours.
