Abstract

The properties of cordierite, 2MgO·2Al2O3·5SiO2, makes this ceramics nowadays an attractive material, which can be used for various applications in electronics. As the sintering temperature of cordierite is very high (1375 °C), any decrease in the temperature at which cordierite is formed leads to economic benefits. Therefore, in this study, the mechanochemical activation of the initial components mixture for the synthesis of cordierite was applied with the aim to lower its sintering temperature. The effects of mechanochemical activation on the cordierite mixture were investigated. Changes in the specific surface area of the activated components were determined by the BET method. The TG method and mass loss were used to monitor the temperature- induced changes in the analyzed threecomponent system. Based on the obtained results, increase in specific surface area and weight loss with increasing activation time, a decrease in cordierite sintering temperature is expected.

Kordijerit, 2MgO·2Al2O3·5SiO2, zbog svojih svojstava predstavlja izuzetno atraktivan keramički materijal koji se može primeniti u elektronici za različite namene. Kako je temperatura sinterovanja kordijerita veoma visoka (1375 °C), svako sniženje temperature na kojoj se formira kordijerit donosi ekonomski benefit. Zbog toga je u ovom radu primenjena metoda mehanohemijske aktivacije smeše polaznih komponenti za sintezu kordijerita sa ciljem sniženja njegove temperature sinterovanja. Ispitivani su efekti mehanohemijske aktivacije na kordijeritnu smešu. Povećanje specifične površine aktiviranih polaznih komponenti je praćeno BET metodom. TG metoda i gubitak mase primenjeni su za praćenje promena uslovljenih temperaturom u analiziranom trokomponentnom sistemu. Na osnovu dobijenih rezultata, povećanja specifične površine i gubitka mase sa povećanjem vremena aktivacije, očekuje se sniženje temperature sinterovanja kordijerita.
