摘要：

The　investigation　on　laser　sintering　of　LiNbO3　ceramics　is　reported.　The　green　patch　of　LiNbO3　ceramic　was　sintered　by　a　150　W　CO2　laser,　with　sintering　temperature　around　980°C.　Compared　with　that　sintered　by　conventional　solid　state　reaction　technique,　the　dielectric　permittivity　of　the　LiNbO3　ceramic　sintered　by　laser　is　lower,　polarization　of　the　ceramic　is　easier,　and　the　piezoelectric　constant　d33　is　6　pC/N.　By　using　the　XRD,　SEM　and　Raman　spectra,　the　phase,　micro-structure,　and　the　mechanism　of　property　modification　in　laser　sintered　LiNbO3　ceramics　were　analyzed.
