The aim of this work was to synthesis via melt cooling crystalline phase (cordierite ceramics) from compositions containing two Algerian kaolinite from east Algeria (kaolin (DD1) rich in Al₂O₃ and kaolin (KT) rich in SiO₂) and synthetic magnesium oxide MgO with relative weight ratios of 54/26/20. The samples were characterized by means of the following techniques: thermogravimetry (TG), dierential thermal analysis (DTA), X-ray diffraction and dilatometry in ordre to analyze sintering behavior, identifie phase transformations, and determine kinetic parameters. The average activation energy for cordierite formation determined using non-isothermal DTA (using Kissinger, Boswell, and Ozawa methods) was 717 kJ mol^-1. The value of coecient of linear thermal expansion was close to 20⁻⁶ K⁻¹ for the temperature range from room temperature to 1000 C. The kinetic parameters n and m had values close to 3. Bulk nucleation from a constant number of nuclei was the dominant mechanism in cordierite crystallization, indicating Three-dimensional growth and shows a polyhedron-like morphology controlled by interface reaction.
