About Calcium Sulphate

​

Calcium Sulphate is an inorganic compound naturally found as gypsum (CaSO₄·2H₂O), anhydrite (CaSO₄), or hemihydrate (CaSO₄·0.5H₂O). It occurs as a white crystalline solid or powder, widely available in both natural and synthetic forms. Its structure comprises calcium cations and sulfate anions, giving it strong ionic bonding and excellent thermal stability.

The compound is chemically stable under ambient conditions and nearly insoluble in water. However, depending on its hydration state, it can readily lose or gain water, making it useful in applications that rely on controlled setting or drying properties. This reversible hydration-dehydration behavior is central to its role in plaster and cement formulations.

In industries, Calcium Sulphate is widely used as a filler, drying agent, and setting modifier. It is particularly known for its use as gypsum in construction, where it provides strength and hardness to plaster and wallboard. Its neutral nature and purity also make it compatible for use in food additives and pharmaceuticals, under strictly controlled grades.

Pandora Industries ensures that all supplied Calcium Sulphate batches undergo stringent quality control for purity, moisture content, and particle uniformity. This allows industries to depend on consistent results in every application—from construction and fertilizers to specialty chemicals.

Applications of Calcium Sulphate

​

Below are some of the main sectors where Calcium Sulphate plays a key role:

​

Construction and Building Materials

In the construction sector, Calcium Sulphate is primarily used as gypsum in plaster, drywall, and cement formulations. When mixed with water, it forms a smooth paste that sets into a solid, durable surface. Its controlled hydration rate and binding strength make it indispensable for interior finishes, wallboards, and decorative plasters.

​

Food and Pharmaceutical Industry

High-purity grades of Calcium Sulphate are used as food additives (E516) to regulate acidity, strengthen dough, or fortify calcium content in processed foods. In pharmaceuticals, it serves as a diluent or filler in tablet formulations, thanks to its chemical inertness and biocompatibility.

Fertilizer and Soil Conditioner

In agriculture, Calcium Sulphate acts as a soil conditioner and calcium supplement. It helps improve soil structure, reduces salinity, and provides essential calcium and sulfur nutrients to plants. Its neutral pH and non-toxicity make it ideal for sustainable soil management practices.

Chemical and Industrial Applications

Calcium Sulphate serves as a drying agent and filler in paints, plastics, and rubber manufacturing. It also functions as a coagulant in wastewater treatment and is used to prepare other calcium compounds through controlled reactions in chemical processing industries.

The wide applicability of Calcium Sulphate supplied by Pandora Industries makes it a dependable choice for manufacturers across diverse sectors in India and abroad.
