Market Overview
High purity calcium sulfate is a refined form of gypsum (CaSO4) that has been processed to remove impurities, making it suitable for applications where purity and consistency are essential. The material is used as a filler and extender in paints and coatings, as a coagulant in tofu production, in plaster and drywall manufacturing, and as a source of calcium and sulfur in agriculture. With a 2025 market value of approximately $18.56 billion and a 9.4% annual growth rate, the segment represents a significant and expanding portion of the broader calcium sulfate industry.
- •Used in construction products including plaster, drywall, and cement additives
- •Key agricultural applications include soil amendment and controlled-release fertilizer coatings
- •Pharmaceutical and food-grade grades serve as excipients, calcium supplements, and tofu coagulants
Growth Drivers
The market is benefiting from sustained global construction activity, particularly in residential and commercial building sectors where high purity gypsum-based products are preferred for their consistent performance characteristics. Agricultural demand is rising as farmers seek efficient calcium and sulfur sources to improve soil health and crop yields, while industrial applications in paper manufacturing, paints, and chemicals continue to expand. Infrastructure development programs across emerging economies are further supporting demand for quality construction materials.
