最新发达的 sintering 帮助Na_( 5.6 )Cu_( 1.2 )Sb_( 10 )O_( 29 )( NCS ) andlead-bismuth-free piezoceramics (Na_( 0.5 )K_( 0.44 )Li_( 0.06 ))Nb_( 0.95 )Sb_( 0.05 ) O_3 ( NKLNS )被准备由常规稳固的州的反应。NKLNS 的电的性质上的 sintering 帮助 NCS 的效果被调查。到 NKLNS 的 sintering 帮助 NCS 的合适的数量的增加不仅在改进密度和压电的活动上，而且在减少 NKLNS 的绝缘的损失上是有效的，这被发现。与 0.4 mol% NCS 做的 NKLNS 超过 60% 象 261pC/N 和机电的联合因素 k_(33 ) 一样高有压电的经常的 d_(33 ) 。这些结果证明做 NCS 的 NKLNS 是有希望、适用的候选人 forlead-bismuth-free piezoceramics。

英文摘要：

Newly developed sintering aid Na5.6Cu1.2Sb10O29 and lead-bismuth-free piezoceramics （Na0.5K0.44Li0.06）Nb0.95Sb0.05O3 （NKLNS）were prepared by the conventional solid state reaction. The effects of sintering aid NCS on the electrical properties of NKLNS were investigated. It was found that the addition of a proper amount of sintering aid NCS to NKLNS is effective not only on improving the den- sity and the piezoelectric activity, but also on reducing the dielectric loss of NKLNS. The NKLNS doped with 0.4 tool% NCS has a piezoelectric constant d33 as high as 261pC/N and an electromechanical coupiing factor k33 above 60%. These results show that NCS-doped NKLNS is a promising and practicable candidate for lead-bismuth-free piezoceremics.
