The formation of calcium carbonate from a supersaturated solution doped with trace lanthanum was studied at various temperatures. At a temperature of around 50°C, more than 80% of calcium carbonate precipitated from 5 μmol kg-1 LaCl3, 15 mmol kg-1 CaCl2-NaHCO3 solution was vaterite while from a lanthanum-free solution calcium carbonate precipitated exclusively as calcite.
