چکیده
In this paper, the effects of CuO sintering aids on microstructure and electric properties are investigated for non-stoichiometric (Na0.48K0.473Li0.04Sr0.007)(Nb0.883Ta0.05Sb0.06Ti0.007)O3+x mol% lead free ceramics. As amounts equal 1 mol%, temperature is 975 °C piezoelectric parameters d33 = 200 pC/N, g33 38 (10−3 Vm/N), × 7600 (10−15 m2/N), kp 0.38, Qm 240, Pr 18.93 μC/cm2 EC 8.75 kV/cm. The changed to hard type suitable energy harvester with multilayer technology. physical response mechanisms suggested that diffused phase transitions enhanced, Cu2+ ions substitute B-site forming Oxygen vacancies domain walls pinning.

Effect of Calcination Kinetics and Microwave Sintering Parameters on Dielectric and Peizo-Electric Properties of(K0.5Na0.5) NBO3 Ceramics
An efficient solid-state approach was established to synthesize (K0.5Na0.5) NbO3 ceramics using calcination kinetics and microwave assisted sintering. Milling of carbonate and oxide raw materials were carried out for 15h to obtain homogeneous nano particles. The crystallite size of 5.30 nm was obtained for the KNN system after calcination through optimized parameters and observed to be stoichio...
متن کاملSintering Behavior of 0.8 mol%-CuO-Doped 3Y-TZP Ceramics
In recent years, 3 mol% yttria-stabilized tetragonal zirconia polycrystals (3Y-TZP) doped with copper oxide has obtained increasing interest due to its enhanced superplastisity and good potential in tribological applications. In this work, the effect of addition of small amounts (0.8 mol%) of copper oxide on the sintering behavior of 3Y-TZP was studied using a dilatometer and high-temperature X...
متن کاملPractical classes " Ceramics & Colloids " : TP 3 Sintering 1 TP 3 - Ceramics : Sintering and Microstructure
After the initial molding of the ceramic, whether by slip casting or dry pressing, it is still necessary to densify the compacted powder samples (green bodies) to form a continuous 3D structure and thus to get ceramic pieces appropriate for the selected application. Usually this is done by a sintering process which is a consolidation and densification step of the granular compact through the ac...

The CuO modified (Na0.52K0.48)NbO3 (NKN) piezoelectric ceramics were prepared by a solid-state reaction method. On the one hand, CuO doping can improve the densification behavior and simultaneously promote the grain growth, however, has little effect on the Curie temperature. On the other hand, the mechanical quality factor Qm obviously increases, the dielectric loss tanδ decreases, and the pie...
