Tilted and Twisted Crystals

Classical crystal exhibit smooth and flat facets, they do not tilt. Only few examples are known in which the facets or the crystallographic organization of crystals show twisting or tilting. Employing amorphous calcium carbonate films synthesized by the polymer-induced liquid-precursor (PILP) process, we are able to convert these films into flat cylindrulites with crystallographically complex features. By tuning the experimental parameters, we can generate crystal lattice tilting similar to that found in calcareous biominerals. This contribution, recently published in CrystEngCom evidences the role of spherulitic growth mechanisms in pseudomorphic transformations of calcium carbonate and hints to a hidden role of spherultic processes in vivo.
