    2021-4-25  However, only aragonite-type calcium carbonate with an average particle size of about 40 µm could be obtained selectively when Ca 2+ in the initial solution was 0.02 - 0.06 mol. In the range of 0.02 - 0.06 mol of Ca 2+, the aragonite with the largest average particle size was obtained at 0.03 mol of Ca 2+ in the initial solution. This may be due to the fact that the initial concentration of Ca ions and the
