Calcium Carbonates

Products Photos Catalog Calcium Carbonates Photos Catalog

Calcium carbonate (CaCO₃) is widely used in industries such as plastics, rubber, coatings, and papermaking.

Based on production methods and physical properties, it is classified into Light Calcium Carbonate (PCC - Precipitated Calcium Carbonate) and Heavy Calcium Carbonate (GCC - Ground Calcium Carbonate).

These two types have significant differences in production, characteristics, and applications.

1 - Light Calcium Carbonate (PCC - Precipitated Calcium Carbonate) 1.1 Production Process

Light calcium carbonate is a chemically synthesized product, produced through the lime calcination and carbonization method: Calcination: CaCO₃ → CaO + CO₂ (heated to 900~1000°C) Hydration: CaO + H₂O → Ca(OH)₂ Carbonation: Ca(OH)₂ + CO₂ → CaCO₃↓ (precipitation of ultra-fine calcium carbonate) 1.2 Key Characteristics

Smaller particle size (nano-scale, typically 50-500 nm)

Regular particle shape (cubic, spherical, or needle-like)

High whiteness and purity

Lower density (due to porous structure)

Better dispersion in liquids 1.3 Applications

Plastics & Rubber: Improves product strength, whiteness, and processing performance

Coatings & Paints: Enhances brightness and opacity

Papermaking: Used as a filler to improve printing quality and reduce production costs

Pharmaceuticals & Food: Used as a calcium supplement or food additive
