Abstract:We show that fully dense nanocrystalline titanate ceramic could be obtained by full crystallization from glass which was prepared by a novel contactless solidification process. Through annealing above glass transition temperature T g for prescribed duration, BaTi 2 O 5 ceramic with grain size of 20-130 nm was successfully fabricated. The dependence of the nanoceramic's dielectric constant and dissipation on frequency was investigated. The results show clearly that the dielectric constant of BaTi 2 O 5 nanoceramic depends on average grain size in nanometer scale, and an optimal range of the grain size is found which exhibits greater dielectric constant than conventional microcrystalline ceramics. The as-fabricated ceramic also possesses lower dielectric dissipation, which can be mainly attributed to the presence of nanometer-sized grains.

“…PZT‐based material compositions can be obtained by wet chemical methods like sol–gel, coprecipitation, hydrothermal, etc., and dry methods like solid‐state route or mechanical activation (MA) processes . MA may lead to superior properties compared to conventional solid‐state or wet chemical routes due to combined effect of mechanical energy and temperature that takes place along with reduction in particle size to nanometer scale thereby skipping the calcination stage of conventional mixed oxide route .…”

“…In the course of time, it was also widely used by several researchers for the preparation of nano‐PZT‐based materials. Effect of MA parameters like duration, rpm, etc., on structural, dielectric, and piezoelectric properties were studied for PZT at morphotropic phase boundary (MPB), Gd‐doped PZT, PMN–PZT‐based compounds, FeNbLi‐doped PZT, La‐doped PZT, etc., and for lead‐free materials like strontium bismuth titanate …”

Nanostructured Pb0.98La0.02(Ni1/3Sb2/3)0.05[(Zr0.52Ti0.48)0.995]0.95O3 ferroelectric ceramic has been synthesized for the first time by columbite precursor method followed by mechanical activation (MA) from 5 to 40 h of dry oxide powders using high‐energy ball mill, thereby evading the calcination stage. Progressive perovskite phase formation and transformation by MA were investigated from X‐ray diffraction (XRD) analysis, indicating the noticeable presence of perovskite phase after 10 h of milling. Particle morphology of the powder was analyzed by HRTEM and correlated with activation time. Furthermore, the effect of activation time on microstructure and piezoelectric properties of the samples sintered at 1220°C were investigated. Compact microstructure, composition at morphotropic phase boundary, optimum tetragonality, and crystallinity obtained for the sintered samples resulted in best possible piezoelectric charge coefficient, d33 (449 × 10−12 C/N), piezoelectric voltage coefficient, g33 (32 × 10−3 m.V/N), and figure of merit for power harvesting, FoMPH (14.4 × 10−12 m‐V.C/N2), for 10 h of activation. The experimental data on output voltage in response to simulated random vibrations of aerospace vehicles measured in frequency band of 20–2000 Hz were also optimum for 10 h activation, which confirm the suitability of this composition for power‐harvesting applications.
