What Are the Different Types of Calcium Carbonate Powder?
As an established Calcium Carbonate Powder manufacturer, Sudarshan Group produces different grades, each designed for specific performance and application requirements.
Ground Calcium Carbonate (GCC)
Ground Calcium Carbonate is produced by mechanically processing natural minerals such as limestone, marble, and chalk. It is widely used in construction, paints, plastics, and animal feed applications.
Precipitated Calcium Carbonate (PCC)
Precipitated Calcium Carbonate is chemically produced by reacting calcium oxide with carbon dioxide. Its controlled particle size and high brightness make it suitable for pharmaceuticals, cosmetics, food, paper, and plastics.
Activated Calcium Carbonate
Activated Calcium Carbonate is surface-treated to improve dispersibility, wettability, and compatibility with polymers. It is commonly used in rubber, plastics, and performance-focused applications.
Nano Calcium Carbonate
Nano Calcium Carbonate contains particles in the nanometer range, providing high surface area and improved mechanical properties. It is used in coatings, adhesives, sealants, and polymer applications.
Food Grade Calcium Carbonate
Food Grade Calcium Carbonate is a high-purity grade manufactured to meet food safety requirements. It is used for calcium fortification, dietary supplements, antacids, and food enrichment.
Pharmaceutical Grade Calcium Carbonate
Pharmaceutical Grade Calcium Carbonate offers high purity and consistent quality to meet relevant pharmacopoeia requirements. It is commonly used in tablets, antacids, and pharmaceutical formulations.
Industrial Grade Calcium Carbonate
Industrial Grade Calcium Carbonate is available in different particle sizes and purity levels according to application needs. It is used in cement, ceramics, glass, and other industrial processes.
Coated Calcium Carbonate
Coated Calcium Carbonate is treated with stearic acid or other fatty acids to provide a hydrophobic surface. It improves flow and processability in plastics, rubber, and composite materials.
Calcined Calcium Carbonate
Calcined Calcium Carbonate is heated to decompose into calcium oxide and carbon dioxide. The resulting reactive material is used in chemical manufacturing and processes requiring calcium oxide.

Industries That Rely on Our Calcium Carbonate Powder
From formulation cost-savings to functional performance, our Calcium Carbonate Powder grades are engineered around what each industry actually needs from a mineral filler.
Paints & Coatings
Used as an extender that boosts opacity and brightness while helping formulators control viscosity at a lower overall cost.
Paper & Printing
GCC and PCC grades act as coating pigments and fillers that improve sheet smoothness, brightness, and printability.
Non-Woven Fabric
Used as a mineral filler that adds stiffness and uniformity to non-woven fabric production.
Rubber Compounding
Improves tensile strength, hardness, and elongation properties in finished rubber compounds.
Adhesives & Sealants
Functions as a rheology modifier and bulk filler in sealants, mastics, and industrial adhesives.
Plastics & Films
Coated grades improve film stiffness and light diffusion control while reducing material cost per kilo.
