  • A novel concept in the growth and design of anhydrous

    A novel approach designated as the particle-mediated nano-scale aggregation route to the formation and growth of spherical and colloid-sized anhydrous carbonate mineral particles and hierarchically organized biomineral carbonate structures is discussed. This model is inconsistent with the conventional crystallization mechanism which is primarily based on diffusion growth.

    The occurrence and formation of calcium carbonate minerals is in most cases related to precipitation from aqueous solution where mineral growth proceeds along different pathways. The formation of ACC and its transformation to crystalline calcium carbonate (e.g. (Mg-)calcite aragonite) is a key process in the formation of many biominerals.
