Original Abstract

Lead-free piezoelectric compositions based on (Ba,Ca) (Zr,Ti) O3 have been reported to exhibit many piezoelectric properties similar to the conven-tionally used Pb(Zr,Ti)O3 materials, and have thus been attracting much attention as potential replacements for lead-based piezoceramics. However, there appears quite a wide variation in the reported piezoelectric propertiesoftheBCZTceramics,indicatingthatsuchpropertiesmaybesensitive to fabrication and processing methods. Thispaperreportsaninvestigationofawiderangeofprocessingfactors,includingcomposition(e.g.ratio of Ba(Zr,Ti)O3 to (Ba,Ca)TiO3), sinteringconditions(temperatureandcoolingrate),particlesizeofthecalcinedceramicpowder,structureand microstructure (e.g.phase,latticeparameters,densityandgrainsize),andtheireffectonthepiezoelectricproperties.Forindividualcompositions, lattice constants and grain size,whicharethemselvesdependentontheceramicpowderparticlesizeandsinteringconditions,havebeenshownto be very importantintermsofoptimisingpiezoelectricpropertiesinthesematerials
