Abstract

The dielectric properties such as the real € I and imaginary E" parts of the complex permittivity and the spontaneous polarization P of ceramic Pb(Fe Ta 10 with the diffuse 3hase transition (DPT)ld&el&as&ed under pressures up to Gkbar. The value of & ' shows a broad maximum at a temperature T (mean Curie temperature). As the pressure increases ,(Fm of the maximum in E ' ( E ' ) and the value of tomax decrease,and the shapema? the maximum in E' around T becomes broader. ?he pressure coefficiert of T ismabout -3.PK/kbar. ?he temperature and presyure dependence of f.' and P o f a phenomenological theory usbg statistical treatments based on a gsussian distribution of the local Curie temperature. The value o f the standard deviation rdescriking the intensity of the DPT is 25K and increases with increasirg pressure. is explained in terms
Pb(Fel/2Tal/2) o3陶瓷的耐压介电性能
在高达Gkbar的压力下,研究了具有扩散3相转变(DPT)ld&el的陶瓷Pb(Fe Ta 10)的介电性能,如复介电常数的实部和虚部以及自发极化P。值& '在温度T(居里平均温度)处显示出广泛的最大值。随着压力的增加,E′(E′)中Fm的最大值和tomax的值减小,形状为?E'在T附近的最大值变宽了。T的压力系数约为-3.PK/kbar。? f与温度和压力的关系。和P o的现象学理论使用基于局部居里温度的高斯分布的统计处理。描述DPT强度的标准偏差值为25K,随压力的增加而增加。用术语来解释
