Precipitated Calcium Carbonate (PCC) - created by man in a matter of hours Calcium carbonate can also be produced synthetically in the form of Precipitated Calcium Carbonate (PCC). PCC is created through the conversion of limestone into CaO and CO 2 and the subsequent reaction of both purified components in a chemical reactor.


The components of the urinary calculus including carbonate are carbonate apatite and calcium carbonate such as calcite. Although the latter is reported to be very rare component in human urinary calculus, the results by infrared spectroscopy often show that calcium carbonate is included in calculus.
