Application

Calcium silicate serves a diverse range of industrial and commercial purposes due to its unique properties. Primarily, it functions as an anticaking agent, effectively enhancing the flowability of products like salt and baking powders, even under high humidity conditions. This compound, typically found in both crystalline and amorphous forms, consists of various combinations of calcium oxide and silica, such as tricalcium silicate and dicalcium silicate. Beyond food applications, calcium silicate is essential in the production of building materials, acting as a crucial component in cement clinker. Additionally, it is utilized in the pharmaceutical industry to ensure the free flow of products by absorbing moisture, as well as serving as a filler aid and antacid in oral pharmaceuticals. Its versatility extends to high-temperature insulation materials, replacing asbestos safely, and is also used in cosmetics and agricultural pesticides, among other applications.
