15.07.2018· In the present study, we demonstrate a simple technique to synthesize calcium carbonate chain-like nanoparticles with high aspect ratios; we introduced CO 2 gas into aqueous slurry of calcium hydroxide (lime milk) with addition of a small amount of lime milk during the reaction. Primary particle structures and agglomeration states of the chain-like particles were

Calcium hydroxyapatite (Ca–HA) is a versatile material which can be used in several applications. This study aimed to investigate the one-step synthesis of Ca–HA using solely calcium carbonate as-is and orthophosphoric acid as widely available and low cost initial reactants. The stirring rate and quantity of water had only some slight effects on the reaction rate.

The synthesis of precipitated calcium carbonate nanoparticles with the use of double water in oil emulsion has been developed. Restricting the mass of calcium ions present in the system makes it possible to predict particle size precipitated. A model was developed to calculate the concentration required to synthesize a desired particle size. This model took into account a coalescence factor
