Differential Thermal Method for determining Reactivity of Calcium Oxide

Article metrics


IT has been reported1 that the extent to which the reaction proceeds is influenced by the reactivity of the calcium oxide. The possibility that both this and the analogous reaction might be used for determining the reactivity of calcium oxide was systematically investigated, using differential thermal analysis. A hydration calorimetric technique and determinations of specific surface area by nitrogen adsorption were used for comparative purposes.
