This method can be adapted for the synthesis of submicron calcite particles from conventional chemical precipitation processes. Compared to the particle sizes obtained in the absence of additive Ca 2+ ions, the proposed approach can result in over 90% growth inhibition. Indeed, the extent to which it can be deployed is constrained by the limited solubility of Ca(OH) 2 . Nonetheless, it is simple procedure for the synthesis of colloidally stable and monodisperse calcite particles in conditions of high degrees of supersaturation. While this study was carried out under free-drift conditions, it is likely that further growth inhibition may be achievable by maintaining a high pH and concentration of additive Ca 2+ ions in the growth-inhibiting solution.
