Study of the kinetics of the mechanism of solid-state reactions at increasing temperatures

Possible reasons for the misinterpretation of non-isothermal kinetics are discussed. The importance of the correct selection for the assessment of the progress of the reaction and the acquisition of representative experimental data, as well as the effect of non-isothermal conditions and possible change of the equilibrium on the kinetic equation are stressed. Detailed attention is given to the probable mechanisms of individual cases of solid-state reactions as expressed in integral and/or differential forms of kinetic equations. Reactions controlled by the movement of phase boundaries, by simple nucleation. by nucleation followed by nuclei growth and by diffusion are discussed; a combined form of differential equation suggested for the preliminary. appraisal of possible mechanisms is
