Abstract:
The size of crystallites of oxide, formed by thermal decomposition of MgCO 3 or CaCO 3 , depends from the temperature and the CO 2 pressure during the formation. The crystallite size obtained under certain conditions is a result of the superposition of the rate of formation of nuclei on the carbonate surface and the rate of growth of the oxide particles. It is postulated that the oxide nucleation is the rate determining step of the process. Dissolving the oxide does not change the reaction valocity and therefore the decrease of the reaction velocity cannot be caused by a delaying action of the oxide layer but results from the decrease of the carbonate surface and from tho different reactivity of the carbonate crystals.
