Gypsum (CaSO₄·2H₂O) – Premium Iranian Calcium Sulfate for Global Industries

Gypsum (chemical formula CaSO₄·2H₂O) is a naturally occurring mineral recognized for its versatility, purity, and reliability across numerous industrial applications. This calcium sulfate material is used to regulate cement setting time, improve soil properties, and serve as a major ingredient in construction and manufacturing processes. Its consistency, eco-friendliness, and cost-effectiveness have made it one of the most widely utilized non-metallic minerals worldwide.

At Call2Supply, we offer premium Iranian calcium sulfate products in several forms — including raw gypsum stone, fine powder, calcined gypsum, and agricultural grade — designed to meet international quality standards. Each product undergoes strict quality inspection to ensure ideal whiteness, moisture content, and composition for specific industrial applications.

Industrial Applications

Construction and Building Materials:
This mineral is essential for plasterboards, plasters, decorative panels, and false ceilings. Due to its smooth texture and natural fire resistance, it is widely used for interior design and architectural finishing.

Cement Production:
A vital additive in Portland cement, it acts as a set-time regulator. Its presence ensures better workability, prevents flash setting, and enhances cement durability. Iranian deposits are known for their uniform composition, making them ideal for cement factories.

Agriculture:
As a soil amendment, it helps improve structure, reduce salinity, and provide essential calcium and sulfur nutrients. Farmers use it to enhance crop yields and soil productivity under different climatic conditions.

Ceramics, Paints, and Fillers:
In ceramics and paints, this mineral functions as a filler and casting aid. It improves the smoothness and uniformity of finished products, making it suitable for high-end industrial and artistic applications.

Medical and Dental Fields:
Processed forms are used for orthopedic casts and dental molds due to their purity, quick setting, and fine texture.
