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.
