Abstract

Li doped sodium-potassium niobate (Na_0.5K_0.5)_1-yLi_yNbO₃ ceramic pellets, with y = 0 to 7 (mole) %, were prepared by solid state reaction method with double sintering. With varying lithium content (y), dielectric properties, and X-ray diffraction (XRD) peaks shifting pattern exhibit strong compositional dependence. Among the prepared Composition, a break in XRD peaks shifting tendency, and maximum dielectric constant, electric conductivity were obsreved at the composition with y = 0.06.

锂掺杂对Na1-xKxNbO3介电相区x = 0.500介电性能的影响

摘要

采用固态烧结双反应烧结法，制备了掺锂的铌酸钾钠（Na _0.5 K _0.5）_1-y Li _y NbO ₃陶瓷球团，y = 0〜7 （摩尔）％。随着锂含量（y）的变化，介电性能和X射线衍射（XRD）峰移动模式显示出强烈的成分依赖性。在所制备的组合物中，在y ＝ 0.06的情况下，XRD峰移动趋势的断裂以及最大介电常数，电导率被模糊。
