Abstract

Tuning the pseudomorphic transformation of calcium carbonate allows for the generation of crystal lattice tilting similar to that found in calcareous biominerals.

Highlights

Amorphous calcium carbonate films synthesized by the polymerinduced liquid-precursor (PILP) process convert into crystallographically complex calcite spherulites
Calcium carbonate spherulites formed in solution have been known for more than century; the earliest reports date back to the works of Pieter Harting from 1827, followed by works of T
We show for the first time that calcite spherulites with bent crystal lattice orientation can form via a pseudomorphic phase transformation from a transient amorphous precursor
