Nano Calcium Carbonate is an engineered ultra-fine particulate form of calcium carbonate with particle sizes in the nanometer range. Compared with conventional micron or ground CaCO₃, nano CaCO₃ offers higher specific surface area, improved dispersion, and enhanced surface activity, enabling superior performance in advanced material applications.
Nanoscale Particle Size — Enhanced filler effect and reinforcement
High Specific Surface Area — Better interaction with polymer matrices
Uniform Dispersion — Improves optical and mechanical properties
High Purity & Low Impurities — Stable performance across applications
Tailorable Surface Treatment — Hydrophobic / functionalized options
Eco-Friendly & Safe — Non-toxic, widely accepted mineral
| Item | Specification |
| Appearance | White to off-white powder |
| Particle Size | 20–100 nm (selectable) |
| Purity (CaCO₃) | ≥ 98% |
| Specific Surface Area | 15–50 m²/g |
| Moisture | ≤ 1.0% |
| pH (slurry) | 9–10 |
| Loss on Ignition | ≤ 43–45% |
Surface functionalization improves compatibility with organic polymers:
➡ Hydrophobic Surface Treatment — Improved dispersion in non-polar plastics
➡ Silane Coupling Agents — Enhanced bonding with resin matrices
➡ Organic Coatings — Better processability in coatings and adhesives
Nano CaCO₃ is generally considered safe, but standard handling precautions apply:
Avoid dust inhalation — use masks and local exhaust ventilation
Wear protective goggles and gloves
Keep away from ignition sources (dust may be combustible in air)
