Both slow precipitation, hydrogen carbonate transport at room temperature as well as hydrothermal decomposition of oxalates were used to grow mixed crystals in the system CaCO 3 –MnCO 3 . The limits of the immiscibility gap below 400 °C and the range of metastable formation at low temperatures were investigated Changes of the morphology of the crystals dependent on the temperature of formation and their composition are described.
