Abstract

Free of external disturbance, Ca²⁺ ions stack in the (0001) faces in the mode of (a), corresponding to thermodynamically least stable vaterite phase. To maximally reduce coulomb repulsion under external agitation, one Ca²⁺ ion moves up and the other moves down for one third of interplanar crystal spacing (b), corresponding to the stable calcite phase.
