| 摘要 |
<p>The present invention relates to a piezoelectric ceramic composition for a multi-layer energy harvester and a preparing method thereof, which can enable sintering at a low temperature less than or equal to 900°C, and has a high mechanical quality factor (Qm), a high piezoelectric strain constant, a low dielectric constant and a high electromechanical coupling factor by preparing a piezoelectric ceramic composition for a harvester, which has the formula: (1-x)Pb(Zr_0.47Ti_0.53)O_3-xPb((Ni_1-yZn_y)_1/3Nb_2/3)O_3 + Z mol% MnO_2 + k mol% CuO(0.1<x<0.5, 0.1<y<=0.9, 0.1<=z<=10, 0.1<=k<=10).</p> |
