摘要：

This research was conducted to study influence of ferric oxide nanoparticles on the properties of modified BNKT ceramics. The optimum sintering temperature was 1125 degrees 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 (E = 1689, tan = 0.0606) and mechanical properties (HV = 5.6GPa, HK = 4.9GPa, E = 93GPa and K-IC = 1.58MPa.m(1/2)) was obtained for the 2 vol% sample.
