| Summary: | © 2018, Copyright © Taylor & Francis Group, LLC. This research was conducted to study influence of ferric oxide nanoparticles on the properties of modified BNKT ceramics. The optimum sintering temperature was 1125°C at which all compositions had low porosity (0.12–0.19%). Raman and XRD showed coexisting rhombohedral and tetragonal phases throughout the entire compositional range. The P r , d 33 and g 33 were slightly degraded when the additive was added. The maximum room temperature dielectric (ϵ′ = 1689, tan δ = 0.0606) and mechanical properties (HV = 5.6 GPa, HK = 4.9 GPa, E = 93 GPa and K IC = 1.58 MPa.m 1/2 ) was obtained for the 2 vol% sample. |
