Determination of a partial phase composition in calcined gypsum by calorimetric analysis of hydration kinetics
Original language description
A calorimetric method for the determination of a partial phase composition in calcined gypsum is presented. The method is based on the separation of the reaction heat of the transformation of ?-anhydrite III to ?-hemihydrate from the main hydration reaction transforming ?-anhydrite III to dihydrate. Using the known hydration heats of ?-anhydrite III to dihydrate and ?-hemihydrate to dihydrate, the content of ?-calcium sulfate anhydrite III and ?-calcium sulfate hemihydrate as well as the amount of non-hydrating parts in gypsum can be determined. Practical application of the method is illustrated on three industrial products.
