Vaterite Microdisc Mesocrystals Exposing the (001) Facet Formed via Transformation from Proto-Vaterite Amorphous Calcium Carbonate

, 2020
Vaterite is the thermodynamically least stable phase of the three anhydrous calcium carbonate phases. So far there have been no reports showing the synthesis of pure phase vaterite single crystals exposing the (001) facet without the aid of any additive.

Vaterite in Lake Water [PDF]

Nature Physical Science, 1971
IN a recent communication, Rowlands and Webster1 pointed out that the occurrence of vaterite in nature is extremely rare compared with other forms of calcium carbonate, for example, calcite and aragonite. I wish to report some additional relevant information.

New insight into the stability of CaCO3 surfaces and nanoparticles via molecular simulation [PDF]

, 2014
Using updated and improved atomistic models for the polymorphs of calcium carbonate and their constituent ions in solution, we revisit the question of surface energetics and nanoparticle stability.

Rapid growth causes abnormal vaterite formation in farmed fish otoliths

, 2017
Sagittal otoliths are essential components of the sensory organs that enable all teleost fish to hear and maintain balance, and are primarily composed of calcium carbonate. A deformity, where aragonite (the normal crystal form) is replaced with vaterite,
