Traditional ceramic technology combined with a two-step sintering technique has been applied to prepare 0.96(K0.48Na0.48Li0.04)(Nb0.95Sb0.05)O3-0.04Bi0.5(Na0.82K0.18)0.5ZrO3 (KNLNS-BNKZ) piezoelectric ceramics. The experimental results show that the ceram... see more

The effect of aging on Sr2+ modified Lead Zirconate Titanate (PSZT) ceramics have been studied. Aging was assessed by the measurement of dielectric constant and dielectric loss tangent as a function of time and temperature. Dielectric constant and dielect... see more

The main ferroelectric materials are lead-based which cause serious environmental problem. Then, to develop environment friendly materials, lead-free ceramics derived from BaTiO3 were found to be interesting owing to their attractive ferroelectric perform... see more

 In this paper, influence of additives on structural properties of Tantalum (Ta) doped PZT ceramics, prepared by solid-state oxide and mechanical activation (MA) routes, has been studied. The Fourier transformation infrared spectroscopy (FTIR) studie... see more

Lanthanum doped lead zirconate titanate (Pb1-xLax)(ZryTi1-y)O3 (PLZT x/y/1-y) relaxor ferroelectric ceramics show no macroscopic polarization down to low temperatures as shown by the present dielectric and Raman scattering measurements on PLZT-10/65/35. T... see more

Nonstoichiometric strontium bismuth niobate (Sr0.8Bi2.2Nb2O9: SBN) ceramic was prepared using conventional solid-state reaction and microwave sintering methods. Complex impedance spectroscopy (CIS) has been used to investigate the intra and intergranular ... see more

It was experimentally registered pulsed electromagnetic (EM) radiation in frequency range higher than television one using wideband horns with coaxial and waveguide outputs. The EM radiation was received during shock loading of lead zirconate titanate (PZ... see more

(Bi0.5Na0.5)0.94Ba0.06TiO3 dense ceramics were obtained from autocombustion sol-gel synthesized nanopowders and sintered at 1050 °C for 1–2 h for the study of the electromechanical anisotropy. Measurement of the complex impedance spectrum was carried out ... see more

Different compositions of (Pb1-xLax) (Zr0.60Ti0.40)O3 (abbreviated as PLZT x/60/40; x=0, 0.07, 0.08 and 0.10) ceramics were prepared by a combinatorial approach by high energy mechano-chemical ball milling and cold isostatic pressing (CIP). X-ray diffract... see more
