Electrical properties of clinoptilolite/aluminium oxide/bovine hydroxyapatite composites

Abstract

In current study the electrical properties of clinoptilolite/aluminium oxide/bovine hydroxyapatite composites (Cp/Al2O3/BHA) were analysed. Different concentrations of Cp and Al2O3 (5 and 15 wt% for both Cp and Al2O3) were added to BHA (70 and 90 wt% BHA) and studied after being sintered at 1000, 1100, 1200, and 1300°C for 4 hours under ambient conditions. The dielectric constant (ɛ'), theoretical dielectric constant (ɛ"), dielectric loss factor (tanδ), capacity and conductivity properties were measured on the frequency of 0.1Hz to 10MHz. As the experiment indicates the electrical capacity, loss factor and dielectric values of BHA, CSHA and Al2O3 are high at lower frequencies. While the composite materials, especially the 5wt% Cp and Al2O3 exhibits high stability, smaller amount of change and better conductive properties than pure substances. © 2018 Trans Tech Publications, Switzerland.
