| Abstract: | The piezoelectric properties of A[Pb(1-3x/2-y)LaxCayTiO3]+B TiO2 ceramics were investigated. A high tC ceramics of the third harmonic has been obtained by replacing a proper quantity of Pb with La and Ca, and adjusting TiO2 in free state, and doping Bi, Ce and Cr ions. The ceramics meet the high tC requirement of chip components. The mechanism of increasing tC of PbTiO3 is discussed. |
