Abstract: Needle-like aragonite particles for application in paper industry were synthesised from calcium nitrate solution. Calcium nitrate was prepared from waste lime. Samples of precipitated aragonite were prepared both in batch and flow reactors, respectively. Conditions (concentration of calcium nitrate, temperature, and flow rate of CO2) were optimized for achieving high yield of aragonite in the product.

Keywords: aragonite, precipitated calcium carbonate, calcium nitrate
