Phase transition and electrical properties of high performance, high temperature Bi(mg,Ti)O3-PbTiO3-PbZrO3 relaxor ferroelectric ceramics
Traditional Pb(Mg1/3Nb2/3)O3-PbTiO3 based relaxor ferroelectrics have attracted much attention. However, the relatively low Tm restricts their application in the high temperature range. In the present study, a novel (0.8-x)Bi(Mg1/2Ti1/2)O3-xPbTiO3-0.2PbZrO3 ((0.8-x)BMT-xPT-PZ) relaxor ferroelectric based on the high temperature BMT-PT piezoelectrics was designed. All samples exhibit pure perovskite structures and the phase structures show a gradual transition from relaxor rhombohedral (R) to normal tetragonal (T) phases via the morphotropic phase boundary (MPB) in the composition range x = 0.36–0.39. The dielectric relaxation behavior can be observed in all samples although a spontaneous normal-relaxor ferroelectric transformation is observed in the T phase region. The x = 0.38 sample exhibits the optimal overall electrical properties with the d33 value of 325 pC/N, the kp value of 0.38, the Tm value of 290 oC. The results indicate that the present studied ternary system has a good potential as high temperature relaxor ferroelectrics.
期刊介绍：
While ceramics have traditionally been admired for their mechanical, chemical and thermal stability, their unique electrical, optical and magnetic properties have become of increasing importance in many key technologies including communications, energy conversion and storage, electronics and automation. Electroceramics benefit greatly from their versatility in properties including:
-insulating to metallic and fast ion conductivity
-piezo-, ferro-, and pyro-electricity
-electro- and nonlinear optical properties
-feromagnetism.
When combined with thermal, mechanical, and chemical stability, these properties often render them the materials of choice.
The Journal of Electroceramics is dedicated to providing a forum of discussion cutting across issues in electrical, optical, and magnetic ceramics. Driven by the need for miniaturization, cost, and enhanced functionality, the field of electroceramics is growing rapidly in many new directions. The Journal encourages discussions of resultant trends concerning silicon-electroceramic integration, nanotechnology, ceramic-polymer composites, grain boundary and defect engineering, etc.
