Used as a desiccant due to its ability to absorb moisture, calcium sulfate dihydrate is commonly found in drying tubes and packaging to protect sensitive materials from humidity. In construction, it serves as a key component in plaster and drywall, providing fire resistance and sound insulation. It is also used in agriculture to improve soil structure and supply calcium and sulfur to crops. In food production, it acts as a coagulant in tofu manufacturing and is added as a dietary source of calcium. Additionally, it is employed in dentistry for making dental impressions and molds.
