Calcium stones are the most common type of kidney stones. They are usually made of calcium and oxalate (a natural chemical found in most foods), but are sometimes made of calcium and phosphate. Uric acid stones form when your urine is often too acidic. Uric acid can form stones by itself or

urinary stones are found in the form of brushite, dahllite, hydroxyapatite, whitlockite and octacalcium phosphate. Brushite crystals form urinary stone, promote whewellite (calcium oxalate) stone formation and act as a precursor to form apatite and octacalcium phosphate type urinary crystals . Among all urinary phosphate crystals, brushite has the

Effect of COg2 on the stability of apatite. As can be expected from the reduction in the crystallite size and the increase in strain as a consequence of the incorporation of C032- in the apatite structure, a carbonate-containing apatite will be expected to be less stable compared to carbonate-free apatites.
