Our ProductsCALCIUM CARBONATE
Commonly known as limestone, calcium carbonate is widely used as a cost-effective filler in various industries. Chemically, it is composed of CaCO₃ (calcium carbonate).
Chemical Structure & Composition
- Chemical Formula: CaCO₃
- Naturally occurs as minerals like:
- Calcite (most common)
- Aragonite
- Chalk
- Limestone and marble
Key Properties
- Fine white powder
- Insoluble in water, but reacts with acids
- Stable at ambient temperature, decomposes to CaO and CO₂ at ~825°C
- High brightness and opacity
- Low oil absorption
- Non-toxic and food-safe (in specific grades)
- High hardness and stiffness (especially coated forms)
- Inert and chemically stable
Industrial Applications
| Industry | Application |
|---|---|
| Plastics & Polymers | As a filler in PVC, PE, PP, and other plastics to improve stiffness, reduce cost, and enhance surface finish. |
| Rubber | Filler to improve wear resistance and dimensional stability. |
| Paints & Coatings | Enhances opacity, whiteness, and smoothness; reduces formulation cost. |
| Paper | Used as a filler and coating pigment for brightness and opacity. |
| Adhesives & Sealants | Improves volume, texture, and consistency. |
| Pharmaceutical & Food | Used in antacids, calcium supplements, and as a food additive (E170). |
| Construction | Ingredient in cement, plasters, and as a building material. |
| Agriculture | Soil conditioner (liming agent) and animal feed additive. |
| Cosmetics | Acts as a mild abrasive and absorbent in powders and toothpaste. |
