Calcium Sulfate (CAS 99400-01-8) is a foundational inorganic compound with a rich history and a wide array of essential industrial applications. For chemists, R&D professionals, and procurement specialists, a thorough understanding of its chemical properties is key to leveraging its potential effectively. As a supplier of fine chemicals, we aim to provide insights into the fundamental nature of Calcium Sulfate and its widespread impact across various industries. Whether you are looking to buy Calcium Sulfate for manufacturing or research, understanding its characteristics is the first step.

Chemically, Calcium Sulfate (CaSO4) is a salt composed of calcium cations and sulfate anions. It commonly exists in nature as gypsum (CaSO4·2H2O), a hydrated form. Anhydrous calcium sulfate (CaSO4), also known as anhydrite, is formed when gypsum is heated to high temperatures, losing its water of crystallization. This compound is notable for its relatively high melting point, exceeding 300°C, and its low solubility in water. These properties, along with its stability, make it suitable for numerous industrial applications. When considering purchase, clarifying whether anhydrous or hydrated forms are needed for your specific chemical processes is vital.

The industrial significance of Calcium Sulfate is vast. In construction, gypsum (hydrated Calcium Sulfate) is a primary component of plaster, drywall, and cement. Its ability to absorb and release water upon heating makes it useful for controlling the setting time of concrete and gypsum board. In agriculture, it serves as a soil conditioner, providing essential calcium and sulfur nutrients, and improving soil structure, especially in heavy clay soils. Its low solubility ensures a slow release of these nutrients, preventing over-fertilization.

Beyond construction and agriculture, Calcium Sulfate finds critical roles in other sectors. It's used as a filler in paints, coatings, and plastics, adding bulk and improving certain physical properties. In the food industry, as mentioned earlier, food-grade Calcium Sulfate is a vital coagulant and nutrient supplement. For those in the electronics sector, highly purified forms are essential for photoresist formulations, where its chemical inertness and controlled particle size are beneficial. Any purchase of Calcium Sulfate should be aligned with these varied application requirements.
