摘要

本研究的目的是表征W/sup 6+/-掺杂，0.87 Pb(Mg/sub 1/3/Nb/sub 2/3/)O/sub 3/-0.13PbTiO/sub 3/弛豫铁电体的介电和感应压电性能。诱导的k/sub /s与W/sup +/的数量和电场有很大关系，当外加电场为6 kV/cm，掺杂量为1%时，k/sub /s的最大值为0.58。此外，烧结温度(/spl plusmn/10/spl℃)的微小变化对性能有显著影响，k/sub / t/降低高达10%。

Effect of tungsten additions on the field-induced piezoelectric properties of Pb(Mg/sub 1/3/Nb/sub 2/3/)O/sub 3/-PbTiO/sub 3/ ceramics

The objective of this research was to characterize the dielectric and induced piezoelectric properties of W/sup 6+/-doped, 0.87 Pb(Mg/sub 1/3/Nb/sub 2/3/)O/sub 3/-0.13PbTiO/sub 3/ relaxor ferroelectrics. The induced k/sub t/'s depended strongly on the W/sup 6+/ amount and electric field, maximizing at a value of 0.58 for an applied field of 6 kV/cm and a 1% doping level. In addition, only slight variations in the sintering temperature (/spl plusmn/10/spl deg/C) had a pronounced effect on the properties, decreasing the k/sub t/ by as much as 10%.
