Industrial Calcium Sulf Detailed Specifications
Industrial-Grade Calcium Sulfate is a highly stable inorganic compound available in dihydrate (gypsum), hemihydrate (plaster-grade), and anhydrite (anhydrous) forms. With consistent mineral purity, controlled particle distribution, and excellent structural stability, it is widely used in cement and building materials, fertilizer production, chemical processing, soil improvement, water treatment, and industrial fillers.
Its predictable hydration/dehydration behavior and low impurities make it an essential material across multiple industrial sectors.
