Despite being high wear resistance, bioinert and biocompatible, some of the limitations like poor fracture toughness, lack of bioactivity and electrical conductivity properties restrict the use of monolith alumina as bone replacement material. In this paper, we address one such issue and will demonstrate how addition of CaTiO3 (CT) to nano Al2O3 matrix enhances bioactivity, physical and electrical properties like dielectric constant and electrical conductivity etc. Therefore, the strategy in the current research is to design a dense alumina Al2O3-CT nanobiocomposites using conventional pressure less sintering technique (1400 oC, 2 hours) that can be enhanced the functional properties compared to that of monolith alumina. The microstructural as well as functional characterizations were carried out by using XRD, SEM and impedance analyser. As results, the dielectric constant and electrical conductivity increases with function of frequency and temperature was higher compared to other composites. Finally, the results of in vitro analysis indicate that effect of electrically bioactive Al2O3-CT nanocomposite will be potential candidate materials for electronic interfacing materials for biomedical application.
