In　this　paper,　by　CO2　laser　sintering　technique,　grain-oriented　K0.5Na0.5NbO3-LiTaO3　ceramics　with　high　dense　of　92%　theoretical　density　were　prepared.　The　dielectric,　piezoelectric　and　electromechanical　properties　were　found　to　be　Ε　∼　510,　d33　∼　120　pC/N,　and　kp　∼　36%,　while　with　high　Curie　temperature　of　about　420　°C　and　low　dielectric　loss　of　about　0.030.04.　The　high　dense　(92%　theoretical　density)　structure　with　the　texture　character　of　grain-orientation　is　the　factors　to　obtain　good　piezoelectric　properties　of　the　ceramics.　The　preparation　of　high　dense　ceramic　is　due　to　the　suppression　of　O2　discharged　by　the　coaxial　gas　injection　systems　on　the　volatilization　of　the　K+,　Na+　and　Li+　during　laser　heating.　An　interesting　change　of　grain　shape　from　isometric　to　anisometric　(needle-like)　relating　to　the　grain-orientation　was　observed　obviously　in　the　laser-sintered　KNN-based.　It　was　concluded　that　the　enhanced　Curie　temperature　associated　with　the　high　temperature　phase　transition　was　induced　by　the　instant　adjustment　of　laser　power　density　from　0.07　kW/cm2　to　0.28　kW/cm2　just　during　25　s.
