Thermodynamics and kinetics of thermal dissociation of dolomite

Abstract

The results of investigations into thermodynamic foundations and kinetics of thermal dissociation of dolomites of Ural deposits are presented. Dolomite samples are characteristic of the fraction and coarseness of calcite inclusions, which determines distinctions in their dissociation kinetics. It is established that dolomites dissociate according to the two-stage model limited by the reaction on a three-dimensional surface at the first stage and kinetic equation having the order close to 0.3 and 0.3 at the second stage.
