Abstract: Cubic shaped CaCO3 particles with mean size of 30-40 nm were prepared by intermittent
carbonation process without any additives. It was found that the flow rate of CO2 has no
distinct influence on the particle size larger size.

Key words: nano-size CaCO3, analysis, number of growth unit, agglomeration
