Preparation and Properties of Copper-Substituted Hydroxyapatite Powders and Ceramics

—Hydroxyapatite powders containing up to 2.4 mol % Cu (Cu-HA) have been synthesized via precipitation from solution. The synthesized materials have been characterized by X-ray diffraction after heat treatment in the temperature range from 900 to 1400°C and their lattice parameters and crystallite size have been determined. We have studied the bending strength and microstructure of Cu-HA-based ceramics. The results demonstrate that the addition...
