Wang et al. [39] theoretically investigated the gypsum solubility in the aqueous solutions of MgSO 4 /H 2 SO 4 from 298.1 K to 363.1 K on the basis of the Pitzer model's predictions. It was found that the gypsum solubility values decreased uniformly as the concentration of MgSO 4 increased if the H 2 SO 4 concentration was >0.5 mol/kg. …
The search for effective technological operations to stabilize technical characteristics used in producing gypsum binders has received a great deal of attention in recent years owing to the instability of calcined gypsum properties [1]. Gypsum hemihydrate is a material used in the building industry and produced by means of calcinating gypsum.

Calcium sulfate, commonly known as natural gypsum, is found in nature in different forms, mainly as the dihydrate ( CaSO 4"2H20 ) and anhydrite ( CaS0 4). They are products of partial or total evaporation of inland seas and lakes. Both the dihydrate and the anhydrite occur in nature in a variety of forms.
AGRICULTURAL GYPSUM Dihydrate vs. Anhydrite The highest quality gypsum for agriculture is natural, a dihydrate, has beneficial trace minerals, and purity levels over 80%. Because Dihydrate is already hydrated with water molecules, as opposed to anhydrite, it dissolves faster in water. If dissolved in the irrigation water, dissolution speed has little …
97% Calcium sulfate dihydrate, the purest available on the market. ... LOWER APPLICATION RATES. Other western gypsum sources can require up to 4x more product to get the same results. HIGHLY SOLUBLE . 97% passing 200 mesh and 92% passing 325 mesh means it goes into solution faster and more completely than other sources.
Naturally occurring crystals are calcium sulfate dihydrate, CaSO 4 ·2H 2 O, known as gypsum, and anhydrous calcium sulfate, II-CaSO 4. When gypsum is heated, dehydration occurs to form hemihydrates, CaSO 4 ·1/2H 2 O, followed by anhydrite, III-CaSO 4. The hemihydrates and the anhydrite have two modifications, α and β, respectively.
Calcium sulfate occurs in nature in form of three different minerals distinguished by the degree of hydration: gypsum (CaSO4·2H2O), hemihydrate (CaSO4·0.5H2O) and anhydrite (CaSO4).
