Abstract

Studies of the reactions between solid calcium carbonate and orthophosphate solutions at low partial pressures of carbon dioxide indicated that hydroxyapatite was the stable product formed in these systems. Hydroxyapatite precipitated directly even though dicalcium phosphate formed initially under certain conditions. The reactions with orthophosphate did not seriously disturb the normal calcium carbonate equilibrium with the solution.
