The influence of activation and relaxation time on the synthesis of cordierite ceramics

Abstract

Due to its properties, cordierite, 2MgO·2Al2O3·5SiO2, is nowadays an attractive ceramic material for various applications.Mechanochemical activation of the initial componentswas used in order to decrease the sintering temperature. Changes in the specific surface area of the activated componentswere determined by the BETmethod. The TG andDTAmethods were used to monitor the temperature induced changes in the analyzed 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.
