Abstract

Hydroxyapatite samples where calcium cations are substituted by silver cations have been obtained by mechanochemical method using silver nitrate and phosphate as the sources of substituting ions. Prepared samples have been studied by X-ray diffraction and infrared spectroscopy. On the use of AgNO3, synthesis products contain residual nitrate, while employment of Ag3PO4 allows preparation of monophase silver-substituted carbonate–hydroxyapatite. The introduction of silver cations instead of calcium cations increases parameters of crystal lattice of hydroxyapatite.
