Calcium Carbonate (Calcite) – A Versatile Industrial Mineral

Calcium Carbonate (CaCO₃), commonly known as Calcite, is a widely used functional mineral with applications in paints, plastics, rubber, paper, ceramics, pharmaceuticals, construction, and more. It enhances mechanical strength, opacity, brightness, pH balance, and thermal stability across various industries.

At Ashok Minerals, we supply Precipitated Calcium Carbonate (PCC), Ground Calcium Carbonate (GCC), and Coated Calcium Carbonate, ensuring consistent quality, high purity, and superior performance in industrial applications.

Chemical Properties of Calcium Carbonate

• Chemical Formula: CaCO₃
• Composition: Calcium (Ca), Carbon (C), Oxygen (O)

Physical Properties:

• High brightness and opacity
• Insoluble in water but reacts with acids
• Excellent thermal stability
• Neutral pH, improving chemical balance in formulations
• Available in multiple grades (PCC, GCC, Coated)

Interesting Facts:

1. Essential in Everyday Products: Calcium carbonate is used in toothpaste as a mild abrasive and in antacids to neutralize stomach acid.
2. Fizzy Reaction with Acid: When calcium carbonate reacts with acids (like vinegar), it produces carbon dioxide gas, causing effervescence—this is the basis for fizzing tablets and cleaning solutions.
