Homogeneous nucleation of CaSO ุ 2H O gypsum based on an optical diagnostic 4 2 technique was studied within a supersaturation range of 1แ 4 at 25แ 90ะC. The experiments were carried out using an experimental apparatus consisting of a batch crystallizer with the related measurement deยฎices. Signals
The precipitation of calcium sulphate dihydrate from aqueous solutions has been studied at super-saturations sufficient for spontaneous precipitation but low enough to enable highly reproducible experiments to be carried out with respect to induction periods and rates of precipitation. The induction
## Abstract Precipitation of calcium sulfate dihydrate, gypsum, from (i) a pure sulfuric acid/lime suspension and (ii) a waste sulfuric acid/lime suspension in a continuous pilot plant in the temperature range from 40 ยฐC to 80 ยฐC was studied. It was observed that in the case of waste sulfuric acid
