摘　　要：通过对几种不同的样品压电特性、机械品质因数和介电温谱等特性的对比和分析 ,研究了Pb (Li1/4Nb3 /4 )O3 Pb (Fe1/3 Sb2 /3 )O3 PbTiO3 PbZrO3 四元系陶瓷在不同配比和掺杂下的机电性能 ,发现该系列样品具有较高的压电常数 (可达 3 4 0× 10 -12 C/N)和介电驰豫温谱。文中还对该系列陶瓷的烧成工艺进行了一定的实验和对比 ,以寻找其最佳的烧成工艺。The electric properties of Pb(Li 1/4 Nb 3/4 )O 3 Pb(Fe 1/3 Sb 2/3 ) PbTiO 3 PbZrO 3 quadruple ceramics with different proportions and dopants are investigated by analyzing piezoelectric properties, mechanic quality and the diffusive graph of relative dielectric constant vs temperature of different samples. It is found that the samples exhibit high piezoelectric constant, up to 340×10 -12 C/N, and the diffusive temperature dependence of dielectric properties. To improve the properties, the techniques for preparation and test are also investigated. (9 refs.)
