| Abstract: | Lead-free piezoelectric ceramics 0.94(Na_(0.96-x)K_xLi_(0.04))_(0.5)Bi_(0.5)]TiO_3-0.06Ba(Zr_(0.055)Ti_(0.945))O_3 were fabricated with the variation of K content and their dielectric and piezoelectric characteristics were also investigated.The 0.94(Na_(0.80)K_(0.16)Li_(0.04))_(0.5)Bi_(0.5)]TiO_3-0.06Ba(Zr_(0.055)Ti_(0.945))O_3 ceramics with a piezoelectric strain constant d_(33) as high as 185 pC/N are obtained.The results show that the peak in the dielectric constant curve versus temperature moves rightward with the increase of K content.Accordingly,the temperature corresponding to maximum dielectric constant for the ceramics increases slightly. |
