    C alcium Silicate Powder (CAS No. 1344-95-2) is a white to off-white, free-flowing inorganic powder composed primarily of calcium oxide (CaO) and silicon dioxide (SiO₂), available in both hydrous and anhydrous forms. It features a fine particle size (typically 325–3000 mesh), low bulk density (0.15–0.25 g/cm³), high porosity, and strong water absorption, making it highly versatile across industrial, food, pharmaceutical, and construction sectors.

    This material exhibits outstanding thermal stability, with a melting point around 1540°C and low thermal conductivity (0.05–0.07 W/(m·K) at 200°C), enabling excellent high-temperature insulation and fire resistance. It is insoluble in water, ethanol, and weak alkalis but soluble in strong acids, with a pH range of 8.4–12.5 (5% slurry), ensuring chemical inertness in most working environments. Non-toxic, odorless, and physiologically safe, it complies with food-grade and pharmaceutical-grade standards, supporting use in direct food and drug applications.

    In the food industry, Calcium Silicate Powder serves as an approved anticaking agent (INS 552/E552) to maintain flowability of powdered products such as spices, seasonings, milk powder, and sugar. It also acts as a reliable filter aid and processing aid to improve clarity and production efficiency. For pharmaceuticals, it functions as an excipient, enhancing powder flow, tablet compressibility, and formulation stability.

    In industrial and construction applications, it is widely used in lightweight thermal insulation, refractory materials, fireproof coatings, and building composites. Its low density and high strength improve dimensional stability and energy efficiency in panels, pipes, and equipment insulation. As a functional filler in plastics, rubber, and paints, it reinforces mechanical properties, enhances weather resistance, and extends service life. It also supports ceramics, glass manufacturing, and environmental remediation due to its stable structure and adsorption capacity.

    Our Calcium Silicate Powder is manufactured under strict quality control, offering consistent particle size distribution, high purity (up to 98%+), and batch-to-batch uniformity. Custom grades are available for food, pharma, and industrial uses to meet specific processing and performance demands. Eco-friendly, non-corrosive, and safe for long-term use, it is a trusted material for modern manufacturing and engineering solutions.
