Nanocomposites of Sodium Potassium Cerium Titanate at Morphotropic Phase Boundary as a Green Material for Piezoelectric Transducer and Actuator Applications

  • Abstract:
  • New lead-free piezoceramic nanocomposites of Sodium Potassium Cerium Titanate (NKCT) with general formula (1-x) K0.5 Ce0.5 TiO3 - x Na0.5 Ce0.5 TiO3), exhibiting a Morphotropic Phase Boundary (MPB), have been synthesized following hydrothermal method followed by solid state sintering. The occurrence of MPB at the composition with x=0.66, at which rhombohedral and monoclinic phases are found to coexist, has been confirmed using powder XRD. This accounts for the occurrence of large remnant polarization when the sintered ceramic pellets are subjected to electric poling at 2KV/mm. Uniform microstructure of various compositions is confirmed by SEM imaging. Dielectric and piezoelectric properties of the samples are found to be comparable to those of commercial grade PZT. At the MPB, the d33 coefficient is found to be 208 pC/N, which is close to that of commercial grade PZT, which makes NKCT a promising material to substitute lead containing PZT in the near future. The thermal properties viz thermal diffusivity, thermal effectivity, conductivity and specific heat capacity were measured using a novel indigenous technology and reported.
