Synthesis of Nano Calcium Carbonate Structure and Characteristics

The precipitation and formation of calcium carbonate (CaCO?.) nanostructures from CaCl2 and Na?CO? solutions were studied. Maintaining a high pH level was shown to be a key factor in ensuring the stable presence of carbonate ions and preventing the formation of soluble bicarbonate forms. DLS data indicate that the formed calcium carbonate consists of nano-sized structures. The results obtained confirm the importance of controlling pH, reagent ratio, and carbonate ion concentration to purposefully control the morphology and structure of nanocrystals.
