Due to its properties, cordierite, 2MgO . 2Al2O3 . 5SiO2, is nowadays an attrac- tive ceramic material for various applications. Mechanochemical activation of the initial components was used in order to decrease the sintering temperature. Changes in the spe- cific surface area of the activated components were determined by the BET method. The TG and DTA methods were used to monitor the temperature induced changes in the ana- lyzed three-component system. The influence of the relaxation time on the activated components was analyzed by FTIR spectroscopy of both the initial components and the activated mixture after 24 h and 24 months relaxation periods.
