摘要：

Phases, domain configuration, and properties of 0.65Pb(Mg1/3Nb2/3)O-3-0.35PbTiO(3) ceramics with grain sizes of 4 and 0.15 mu m have been studied. The average phase is monoclinic Pm in coexistence with tetragonal. An evolution from micron-sized lamellar domains towards submicron/nanometer sized crosshatched domains is found with the decrease in size, which results in electrical relaxor type behavior and hindered switching. This is proposed to be associated with the slowing down of the relaxor to ferroelectric transition that causes the long time presence of an intermediate domain configuration. Nevertheless, a high sensitivity piezoelectric submicron-structured material is obtained under tailored poling (d(33)similar to 300 pC N-1).
