Apstrakt

Zahvaljujući svojim svojstvima, kordijerit, 2MgO·2Al2O3·5SiO2, danas je atraktivan keramički materijal za razne primene, ali sa vrlo visokom temperaturom sinterovanja. Mehanohemijska aktivacija smeše početnih komponenti izvedena je da bi se snizila temperatura sinterovanja. DTA metoda je korišćena za praćenje temperaturnih promena u analiziranom trokomponentnom sistemu. Kako je ranijim istraživanjima utvrđeno da vreme relaksacije može da utiče na aktivirane komponente u smislu hemijskih promena i stepena aktiviranosti, bilo je značajno utvrditi ima li uticaj i na posmatrani aktivirani system. Uticaj vremena relaksacije na smešu aktiviranih komponenata analiziran je FT IR spektroskopijom i početnih komponenti i aktivirane smeše nakon 24h i 24 meseca perioda relaksacije.
