Description	Kinetic studies were performed on two types of leucite precursors. These precursors were prepared using a hydrothermal method at 150 degrees C; the reaction time was 1.5 hours. In order to obtain precursors having different amounts of seed the molarity of KOH was changed. These intermediate products were subsequently calcinated from 5 minutes to 72 hours at temperatures of 850 degrees C, 900 degrees C, 950 degrees C, 1000 degrees C and 1050 degrees C. The crystallinities of the powders were calculated by X-ray diffraction analysis. The crystallization curves for the synthesis of leucite exhibited a typical sigmoidal characteristic. Using different kinetic equations it was found that the Avrami-Erofeev model is the most appropriate to describe the experimental data. Using the Avrami-Erofeev model n reaches an average value of 2.9 which is connected with the three-dimensional growth of nuclei. Kinetic studies were performed on two types of leucite precursors.
