Hydroxyapatite-barium titanate piezocomposites with enhanced electrical properties

The present work aims to obtain Hydroxyapatite (HA) – Barium Titanate (BT) piezocomposites with improved electrical properties by retaining OH-ion and tuning BT grain size. Dense piezocomposites of HA-BT were obtained using single step Spark Plasma Sintering (SPS). The presence of OH-ions in the sintered piezocomposites of HA-BT was confirmed by high-temperature X-ray diffraction and Fourier transform infrared transmittance. No decomposition/ interaction between HA and BT phases were observed in the complete range of temperature studied. The dielectric and pyroelectric properties were studied as a function of temperature (100 K to 450 K) and frequency (100 Hz to 2 MHz). The influence of the ferroelectric grain size (300 and 500 nm) on the electrical properties of HA-BT has been analyzed. The dielectric permittivity of HA-BT ceramics can be enhanced with appropriate ferroelectric grain size and volume fraction of BT (<80%).
