| Abstract: |
The kinetics of formation of barium titanate from banum carbonate and titanium dioxide have been studied using isothermal and dynamic thermogravimetry techniques. Kinetic analysis of the isothermal data, considered from the point of view of various solid state reaction models, showed that the reaction is best described by the random nucleation Avrami equation Analysis of dynamic TG data, according to the integral methods of Coats and Redfern and of Ozawa, gave results which are not in agreement with each other or with the results obtained under isothermal conditions. |
