The formation of gehlenite and anortite in the ceramics body.
Matysová, Dorota ; Šoukal, František (referee) ; Ptáček, Petr (advisor)
This bachelor thesis deals with the study of mechanism and kinetics of gehlenite and anorthite formation in the ceramic body. Methods used for this study were thermal analysis (TG-DTA-EGA), HT-XRD and heating microscopy. The Kissinger equation which belongs to the mechanism-free isoconversional methods was used for the determination of the activation energy, the pre-exponential factor and the Avrami coefficient. Characteristic of reactants kaoline Sedlec Ia and precipitated CaCO3 (Penta, p.a.) using IR spectrometry, thermal analysis (TG-DTA-EGA), SEM and heating microscopy is also included in this thesis.
