摘要：

A method for determining the real kinetics of solid-state reactions from analysis of the shape of controlled-rate thermal analysis curves is proposed. It is shown that this procedure provides an easy way for discriminating between "n-order", Avrami-Erofeev and diffusion kinetic laws. The theoretical conclusions were checked experimentally by studying the thermal decomposition of anhydrous nickel nitrate. © 1990.
