Product Description

Product Description

Basic Information

  • Chemical Name: Calcium carbonate
  • Molecular Formula: CaCO3
  • Molecular Weight: 100.09 g/mol
  • CAS Number: 471-34-1
  • Natural Forms:
    • Calcite: Most stable hexagonal crystal form (e.g., limestone, marble).
    • Aragonite: Orthorhombic form (e.g., shells, coral).
    • Vaterite: Metastable hexagonal form (rare in nature).
  • Appearance: White powder or colorless crystals (natural forms may have impurities, showing colors like gray or yellow).
  • Physical Properties:
    • Density: 2.71 g/cm³ (calcite), 2.93 g/cm³ (aragonite).
    • Melting Point: Decomposes at 825°C (releases CO2, forming CaO).
    • Solubility: Insoluble in water (0.0013 g/100 mL at 25°C), soluble in acids (e.g., HCl, forming CaCl2 + CO2 + H2O).

Chemical Properties
  • Thermal Decomposition:CaCO3825CCaO+CO2
  • Acid Reaction: Releases carbon dioxide in the presence of acids, a key property for applications like antacids and CO2 production.
  • Water Interaction: Reacts with dissolved CO2 in water to form soluble calcium bicarbonate:CaCO3+CO2+H2OCa(HCO3)2
    This equilibrium drives natural processes like cave formation (stalactites/stalagmites).

Applications Across Industries
Industry Role and Examples
Construction - Building materials: Limestone as aggregate in concrete; marble for flooring and sculptures.
- Mortar and plaster: Mixed with sand and water for bonding bricks.
Paper Manufacturing - Filler to improve opacity, brightness, and printability (e.g., in coated paper for magazines and packaging).
- PCC is preferred for its uniform particle size.
Plastics & Polymers - Filler and reinforcing agent in PVC, polyethylene, and rubber products (e.g., pipes, cables, automotive parts).
- Improves rigidity, heat resistance, and dimensional stability while reducing costs.
Pharmaceuticals & Food Antacids: Neutralizes stomach acid (e.g., Tums, Rolaids).
Calcium Supplements: Source of dietary calcium (e.g., in tablets or fortified foods).
Food Additive: Anticaking agent, pH regulator, or calcium fortifier (e.g., in cereals, dairy products).
Paints & Coatings - Filler to enhance viscosity, hiding power, and durability (e.g., in latex paints and primers).
Environmental - Flue gas desulfurization (FGD) in power plants: Absorbs SO2 to form gypsum (CaSO4·2H2O).
- Water treatment: Neutralizes acidic water or precipitates heavy metals.
Agriculture - Liming agent to raise soil pH and supply calcium for plant growth.
- Feed additive for livestock (calcium source in animal feed).

Safety and Handling
  • Toxicity:
    • Inhalation of fine dust may cause respiratory irritation (e.g., coughing, dyspnea). Prolonged exposure to limestone dust is linked to pneumoconiosis (rare with modern safety measures).
    • Ingestion of large quantities may cause gastrointestinal discomfort (e.g., constipation, nausea).
  • GHS Hazards:
    • H315 (Causes skin irritation), H319 (Causes serious eye irritation), H335 (May cause respiratory irritation).
  • Handling Precautions:
    • Wear dust masks, goggles, and gloves in dusty environments.
    • Avoid prolonged inhalation; ensure good ventilation during processing (e.g., grinding or mixing).
  • Storage: Store in dry, sealed containers to prevent moisture absorption (minimal reactivity but keeps dust under control).
