As the LE of calcium carbonate is so large, a great amount of free energy would be required to break the strongly attracted ions apart, and this energy has to come from the enthalpy of hydration. In the case of calcium carbonate, the enthalpy of hydration is not large enough to overcome the large lattice energy, hence it exists as a solid. ...

Calcium carbonate (CaCO3) was recovered from the carpet waste by combustion at 500 °C under an air atmosphere. The CaCO3 had a pure calcite phase without detection of other crystalline phases, as confirmed by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) measurements. Dicalcium phosphate (CaHPO4) or …
