GCC is naturally derived, cost-effective, and widely used in construction and general fillers. PCC is synthetically made, pure, and ideal for high-performance applications in industries like pharmaceuticals, cosmetics, and premium paper.
1. Ground Calcium Carbonate (GCC) GCC is a naturally occurring form of calcium carbonate extracted from natural sources such as limestone, marble, or calcite.
Production
Properties
Applications
Raw materials are quarried and crushed into smaller pieces. The crushed material is then ground into fine powder using grinding mills like ball mills or ultrafine mills.
1. Particle Shape: Irregular and angular. 2. Purity: Dependent on the quality of the natural source; may contain impurities. 3. Fineness: Available in a range of coarseness, up to 2500 mesh. 4. Cost: More affordable due to simpler processing.
1. Construction materials (e.g., cement, concrete). 2. Filler in plastics, paints, rubber, and adhesives. 3. Paper coatings for brightness and opacity.
2. Precipitated Calcium Carbonate (PCC) PCC is a synthetic form of calcium carbonate produced through a chemical process.
Production
Properties
Applications
Calcium hydroxide (slaked lime) is reacted with carbon dioxide gas. The chemical reaction forms calcium carbonate, which is filtered, dried, and processed into desired particle shapes and sizes.
1. Particle Shape: Uniform and controlled, can be rhombohedral, scalenohedral, or spherical. 2. Purity: Very high, as impurities are removed during synthesis. 3. Fineness: Extremely fine particles with precise size control, often smaller than GCC. 4. Cost: More expensive due to its chemical production process.
1. High-quality paper (e.g., glossy paper, photocopy paper). 2. Pharmaceuticals (e.g., antacids and calcium supplements). 3. Food and cosmetics (as additives or fillers). 4. Specialty paints, coatings, and rubber products.
