Product Description

Calcium Carbonate (CaCO3)

Calcium carbonate is a naturally occurring mineral compound with extensive industrial, agricultural, and biomedical applications. It exists in three primary crystalline forms: calcite, aragonite, and vaterite.

 

Key Properties

• Chemical Formula: CaCO3

• Molar Mass: 100.09 g/mol

• Appearance: White powder or colorless crystals

• Density:

  • Calcite: 2.71 g/cm³

  • Aragonite: 2.93 g/cm³

• Solubility:

  • Poor in water (0.0014 g/100 mL at 25°C)

• Refractive Index: 1.49-1.66 (birefringent in calcite)

 

Natural Sources & Production

1. Geological Forms:

   • Limestone: Sedimentary rock (primarily calcite).

   • Chalk: Soft, porous limestone.

   • Marble: Metamorphosed limestone.

 

Applications

1. Industrial & Construction
