Furthermore, gypsum serves as a valuable tool for reclaiming sodic soils, where high levels of exchangeable sodium can compromise soil structure and impede plant growth. The application of gypsum effectively displaces exchangeable sodium ions, mitigating sodicity and promoting the restoration of sodic soils to productive and …

Dehydration

When it's hot and humid, your risk of dehydration and heat illness increases. That's because when the air is humid, sweat can't evaporate and cool you as quickly as it normally does, and this can lead to an increased body temperature and the need for more fluids. Complications. Dehydration can lead to serious complications, …

The dehydration process of gypsum under high pressure

At 2.5 GPa, gypsum starts to dehydrate around 428 K, by forming bassanite, CaSO 4 hemihydrate, which completely dehydrates to γ-anhydrite at 488 K.

Dehydration

Having uncontrolled or untreated diabetes puts you at high risk of dehydration. Kidney disease also increases your risk, as do medications that increase urination. Even having a cold or sore throat makes you more susceptible to dehydration because you're less likely to feel like eating or drinking when you're sick. People who …

Gypsum | Definition, Uses, & Facts | Britannica

Gypsum occurs in extensive beds associated with other evaporite minerals (e.g., anhydrite and halite), particularly in Permian and Triassic sedimentary formations; it is deposited from ocean brine, followed by anhydrite and halite.It also occurs in considerable quantity in saline lakes and salt pans and is an important constituent of cap rock, an anhydrite-gypsum …
