在比较分析与实验的基础上，采用添加少量低熔物获得了一种新的低温烧结改性PbTiO3压电陶瓷组成，并对低温烧结机理进行了初步探讨。结果表明，改性PT陶瓷烧结温度可降低200～300℃。960℃烧成时的主要性能参数为kt=0.49，kp=0.027，d33=65×10-12C.N－1，Qm=514，ρv = 7.4×103 kg.m－3，tC= 312℃，εT33／ε0=177，tgδ=0.63%。该材料不仅可抑制铅挥发对环境的污染，还可在叠层压电陶瓷器件方面获得重要应用。

A modified low-temperature sintering PbTiO3 piezoelectric ceramics is obtained by adding small quantity additive of low melt point SiO2. Its sintering temperature reduces by 200～300℃.Of the piezoelectric ceramics sintered at 900 ℃, the main parameters arc kt=0.49, kp=0.027, d33=65× 10-12 C N, Qm=514, ρv = 7.4× 103kg/m3, T= 312 ℃, e33T/ε0 = 177, tgδ. = 063%. The low-temperature sintering mechanism is discussed. The material can be used for stack piezoelectric ceramic devices. With it, PbO volatilization can be restrained.(7 refs.)
