Abstract

In the present work, cation doped hydroxyapatite (HAP) synthesized by sol-gel method. The crystal structure and crystallinity of samples confirmed by powder X-ray diffraction and roughness of prepared samples investigated through the atomic force microscopy. The changes in the dielectric with temperature and frequency are analyzed. Temperature-dependent dielectric property was studied and confirmed that the relaxation occurs with non-Debye-type relaxation. Mechanical properties such as hardness, yield strength, and flexural strength of the ion-doped HAP are studied. The significant improvements were shown in the mechanical property with ion doping for various concentrations.
