Thermal decomposition kinetics of PrM[O.sub.3] ceramic materials via thermogravimetry

Thermogravimetric data using the non-isothermal kinetic models of Flynn and Wall and "Model-free Kinetics" were used to determine the activation energy to study the decomposition kinetics of the ligand groups with system's metallic ions that takes part in the synthesis of PrM[O.sub.3]...

Description
Summary:Thermogravimetric data using the non-isothermal kinetic models of Flynn and Wall and "Model-free Kinetics" were used to determine the activation energy to study the decomposition kinetics of the ligand groups with system's metallic ions that takes part in the synthesis of PrM[O.sub.3] (M = Ni or Co). This activation energy was determined for the stage of highest decomposition of the organic matter to establish parameters in synthesis condition optimization and application of the proposed material.
