Relaxor　based　ferroelectric　single　crystals　Pb(In1/2Nb1/2)O-3-Pb(Mg1/3Nb2/3)O-3-PbTiO3　(PIN-PMN-PT)　with　composition　near　morphotropic　phase　boundary　exhibit　extraordinary　piezoelectric　properties.　Due　to　the　composition　segregation　during　crystal　growth,　the　composition　and　properties　of　PIN-PMN-PT　single　crystal　boules　are　poor　uniformity.　In　this　work,　uniformity　of　dielectric　and　piezoelectric　properties　of　the　crystal　boules　with　4　＇＇　diameter　by　100　mm　long　were　clearly　improved　along　the　crystal　growth　direction　by　the　modified　Bridgman　method.　For　70%　length　of　the　boule,　T-RT　and　T-c　were　around　100　degrees　C　and　160-180　degrees　C　along　the　growth　direction,　respectively.　The　variety　of　piezoelectric　constant　d(33)　is　about　1500-1800pC/N　in　the　same　range　of　the　boule.　So　that　PIN-PMN-PT　crystals　will　be　more　cost-effective　and　beneficial　for　ultrasonic　applications　in　higher　temperature　region.
