High surface area and porous CaCO 3 particles were produced by absorption of CO 2 in aqueous suspensions of Ca(OH) 2 with the addition of a suitable additive at 27 °C and 1 bar. The CaCO 3 surface area was determined mainly by the shape and size of the constituting primary particles. In the absence
