🌟What is Calcium Carbonate?
Chemical Name: Calcium Carbonate
Chemical Formula: CaCO₃
Molecular Weight: 100.09 g/mol
Calcium Carbonate is a naturally occurring inorganic mineral found mainly in limestone, marble, and chalk deposits. It is one of the Earth’s most abundant minerals and is widely used because of its excellent whiteness, high purity, chemical stability, and cost-effectiveness.
Industrially, Calcium Carbonate is available in three major grades:
1. Ground Calcium Carbonate (GCC)
Produced by mechanically grinding high-quality natural limestone or marble.
Features
Excellent brightness
Economical
Controlled particle size
High purity
Ideal for bulk filler applications
2. Precipitated Calcium Carbonate (PCC)
Manufactured through a controlled chemical precipitation process.
Features
Ultra-fine particle size
Superior brightness
Uniform crystal structure
Excellent dispersion
High purity
3. Activated Calcium Carbonate (ACC)
Activated Calcium Carbonate is an advanced surface-treated grade prepared by coating finely processed Calcium Carbonate with Stearic Acid.
This surface modification improves compatibility between Calcium Carbonate and polymer materials, making it an ideal reinforcing filler for plastics and rubber compounds.
