抄録	We report a scalable and template-free production method of mesoporous calcium carbonate particles, of which specific surface areas were 16-207 m2/g, and polymorphs were calcite and/or vaterite. We obtain the transparent colloidal dispersion of calcium carbonate (10 nm less in size) by means of a modified industrial carbonation reaction. Here the effect of oleic acid addition on particle shape, polymorphs, specific surface area, and pore structure of mesoporous calcium carbonate is investigated. The particle properties depend on the additive amount of oleic acid. When the oleic acid was added in small amount to the colloidal dispersion, crystal phase of mesoporous calcium carbonate was calcite. While, the addition in large amount was favorable to form vaterite phase.
