Abstract
Transformations taking place in the system Ca(NO3)2-Na2H2Y-(NH4)2HPO4-NH4OH-H2O during the homogeneous precipitation of hydroxyapatite were studied by means of conductometric, potentiometric and photometric analysis. It was established that the synthesis of hydroxyapatite from the aqueous solutions of calcium and phosphorus salts proceeds as a sequence of several stages, and the use of disodium ethylenediaminetetraacetate promotes the formation of microcrystalline powder with Ca/P ratio close to the biological value (1.67).
