Calcium sulfate precipitation pathways in natural and engineered
Calcium sulfate comprises a group of minerals commonly found in natural and engineered environments. When CaSO 4 is precipitated from aqueous solutions three crystalline phases can be obtained (Fig. 1): gypsum (CaSO 4 ·2H 2 O), bassanite (CaSO 4 ·0.5H 2 O) and anhydrite (CaSO 4).The intersection of the solubility curves of the different hydrates defines the …
