摘要：

Electrical and dielectrical properties of strontium doped hydroxyapatite ceramics have been investigated by impedance and ferroelectric spectroscopy. SEM, FTIR and EDS techniques were used to analyze the chemical and structural properties of Sr doped HaP ceramics. The structural analysis shows that the particles size of HaP and Sr doped biomaterials are in the range of nanometer, i. e., the biomaterials are nanomaterials. Sr doping changes the particle distribution and particle size of HaP samples. The dielectric constants of the ceramics are significantly changed with Sr doping. The polarization vs electric fields plots indicate that Sr doped HaP samples are ferroelectric materials. It is evaluated that the ferroelectric properties of hydroxyapatite is controlled by Sr doping. (C) 2016 Elsevier B.V. All rights reserved.
