About Gypsum (Calcium Sulfate Dihydrate)
Gypsum, chemically known as Calcium Sulfate Dihydrate (CaSO4·2H2O), is a naturally occurring mineral used extensively in industrial applications. It appears as a white to off-white crystalline powder or granules, typically containing more than 90% of the dihydrate form by weight. Industrial buyers should note that gypsum contains about 15.6% crystal water by weight, contributing to its characteristic hydration properties. Supplied in various package sizes including bags and bulk shipments, gypsum requires storage in cool, dry, and well-ventilated areas to prevent moisture-induced degradation. Due to its mineral composition, it must be kept away from incompatible materials such as strong acids or highly alkaline substances. Standard bulk density values range between 900 and 1200 kg/m³, which should be considered for logistic and handling planning.
Why Gypsum (Calcium Sulfate Dihydrate) Matters
In the construction sector, gypsum is essential for producing plaster materials and drywall that offer fire resistance and smooth surface finishes. Its hydration properties allow controlled setting times, which ensure stability during application and curing phases. Agricultural use of gypsum addresses soil calcium deficiencies and improves soil structure by reducing compaction and ameliorating acidity. This improves nutrient uptake for crops, ultimately enhancing yield and soil health. In cement production, gypsum regulates setting times, thereby preventing flash setting and ensuring effective curing.
Available Types of Gypsum (Calcium Sulfate Dihydrate)
Technical Grade GypsumStandard industrial grade suitable for construction and agricultural applications with typical purity over 90%.
Food Grade GypsumComplies with food safety standards for use as a firming agent and calcium supplement in food and feed.
