Abstract：

Pb(Yb1/2Nb1/2)O3-Pb(Zn1/3Nb2/3)O3-PbTiO3(PYZNT)　ternary　crystal　with　pure　rhombohedral　perovskite　phase　was　grown　firstly　by　the　high-temperature　flux　method.　The　composition,　dielectric,　piezoelectric　and　ferroelectric　properties　of　the　crystals　were　studied.　The　actual　chemical　composition　of　the　grown　crystal　is　0.68PYN-0.22PZN-0.1PT.　The　composition,　dielectric,　piezoelectric　and　ferroelectric　properties　of　the　crystal　were　studied,　respectively.　The　dielectric　constant　and　dielectric　loss　exhibit　a　relaxor　behavior　with　respect　to　temperature　and　frequency.　The　Curie　temperature　TC　of　crystal　is　80　℃.　Because　of　high　content　of　antiferroelectric　PYN,　the　crystal　shows　a　huge　coercive　field,　which　makes　polarization　reorientation　could　not　be　finished　even　under　the　external　electric　field　as　large　as　100　kV/cm.　Therefore,　the　saturated　P-E　loop　could　not　be　obtained.　The　piezoelectric　coefficient　d33　for　the　unpoled　sample　is　measured　to　be　78　pC/N.　©,　2015,　Chinese　Ceramic　Society.　All　right　reserved.
