| Products |
| Feature | Benefit |
| High purity | High whiteness Low iron content Low levels of heavy metals Low abrasivity |
| Unique particle shape | Less agglomeration Better flow and rheological properties Lower densityo |
| Narrow particle size distribution | Low abrasivity (virtually no coarse particles) No dust or waste from ultra fine particles Optimum optical properties Relatively low surface areao |
| Product quality independent of raw material | Global specifications Helps achieve 6-sigma process control |
These properties lead to a large number of superior product characteristics suitable for a large number of end markets.
Product selector
Although the SCC process can be used to make a wide range of particle sizes, CalciTech have initially developed products with a mean particle size of 0.9 microns. These are available with different purity specifications and product forms.

Physical Properties
The table below provides some typical values for SCC physical properties.
| Calcium Carbonate Purity | >99.5 % |
| Brightness (ISO) | 97 % |
| Mean Particle Size | 0.9 µm |
| Surface Area | 6 m2/g |
| Specific Gravity | 2.4 |
| Refractive Index | 1.6 |
| Mohs Hardness | 3.0 |
In addition, CalciTech's "solution" carbonation reaction is much faster and more controllable than normal precipitation, allowing for manipulation of particle size and shape not possible with existing commercial processes.
Using this novel process, CalciTech has developed a range of SCC products all with high brightness, narrow particle size distribution and a unique particle morphology comprising of individual crystallites bound together in a rice grain shaped particle.
