Vaterite is the least thermodynamically stable anhydrous calcium carbonate polymorph. It exists very rare in nature, e.g. in some rock formations or as a component of biominerals produced by some fishes, crustaceans or birds. Synthetic vaterite particles are proposed as carriers of active substances in medicines, additive in cosmetic preparations as well as adsorbents. Also, their utilization as a pump for microfluidic flow is also tested. In particular, vaterite particles produced as polycrystalline spheres have a large potential application. Various methods are proposed to precipitate vaterite particles, including the conventional solution-solution synthesis, the gas-liquid method as well as special routes. Precipitation conditions should be carefully selected to obtain a high concentration of vaterite in all these methods. In this review classical and new methods used to vaterite precipitation are presented. Furthermore, the key parameters affecting the formation of spherical vaterite are discussed.
