Background
The ability to control the shape, size and crystalline state of CaCO3 is significant for several industries including:
-
Powder additives- improved flow properties (spherical shape versus irregular) of ink material, rubber filler, and tablet fillers
-
Additives to polymers and plastic improve thermal properties (amorphous material versus crystals)
-
Usage of spheres as template material for drug delivery layer-by-layer methods, simple template for removal.
-
Possibly usage in cosmetics for color or texture improvement
-
Nutrition additive- Potentially has improves bio-absorption (small amorphous nanoparticle compared to the commonly used micro crystals).
