Calcined gypsum definition is - gypsum partially dehydrated by heat; specifically : plaster of paris.
calcined gypsum. Calcined gypsum introduces free calcium ions to form a precipitate of CaF 2. Fluoride ions were removed by 68% at room temperatures. Langmuir isotherm was found to best fit the adsorption behaviour. Thermodynamic parameters such as ΔH0, ΔS0 and ΔG0 indicated that the removal
wallboard, gypsum must be partially dehydrated or calcined to produce calcium sulfate hemihydrate (CaSO4 ½H 2O), commonly called stucco. A flow diagram for a typical gypsum process producing both crude and finished gypsum products is shown in Figure 11.16-1. In this process gypsum is crushed, dried, ground, and calcined.

Gypsum is the crystalline chemical compound CaSO4·2H2O. A close chemical relation – and frequently occurring with Gypsum – is Anhydrite which is CaSO4. Gypsun has wide commercial use because relatively simple heat processing reduces it to Plaster of Paris. While Anhydrite can be converted to Gypsum and thence to Plaster of Paris, the procedure is not simple and is quite costly. Anhydrite ...
