ACCOMMODATION OF THE ACTUAL SOLID-STATE PROCESS IN THE KINETIC MODEL FUNCTION .2. APPLICABILITY OF THE EMPIRICAL KINETIC MODEL FUNCTION TO DIFFUSION-CONTROLLED REACTIONS

摘要

The significance of the empirical kinetic model function for diffusion-controlled reactions is discussed in connection with the fractal nature of the reaction geometry and the macroscopic character of the thermoanalytical curves for solid-state reactions. The mathematical properties of such empirical kinetic model functions based on the geometrical fractal were investigated numerically in order to evaluate their practical usefulness as a possible diagnostic tool for distinguishing the most appropriate kinetic model function. The procedure of distinguishing the kinetic model function is extended, including such empirical kinetic model functions based on the geometrical fractal, and applied to the kinetic analysis of the thermal dehydroxylation of synthetic brochantite Cu-4(OH)(6)SO4.
