CALCIUM SULFATE CAMEO Chemicals NOAA. SOLUBLE ANHYDRITE which is obtained by heating calcium sulfate dihydrate at a temperature below 300C has a high affinity for water and is used as a desiccant Soluble anhydrite absorbs water to form calcium sulfate hemihydrate Plaster of Paris.
Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO4 and related hydrates. In the form of -anhydrite (the anhydrous form), it is used as a desiccant. One particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral gypsum. It has many uses in industry.

2019-3-25 Zinc sulfide is often produced by reacting zinc oxide with hydrogen sulfide, which produces zinc sulfide and water. Another method for producing the chemical is by heating a solution of zinc sulfate with sodium thiosulfate. A third way is to make a equimolar mix of zinc and sulfur powders and ignite the mix.
