摘要
通过对A[Pb(1-3x/2-y)LaxCayTiO3]+B TiO2系统陶瓷的研究,采用La、Ca适量取代Pb和调整适量游离态的TiO2,并通过Bi、Ce、Cr掺杂的办法,得到一种具有较高tC能满足片式元件温度需求的工业用三次谐波PbTiO3陶瓷,同时对改善PbTiO3陶瓷材料tC的机理进行了初步的探讨。
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.
