Abstract: LiNbO₃ is a kind of important ferroelectric and piezoelectric materials with the advantage of high Curie temperature and great of the spontaneous intensity. The characteristics of LiNbO₃ have broad applica tion in light produced by electricity device and in sound surface devices. The research progress of LiNbO₃ powder was reviewed and several meth ods of producing the LiNbO₃ powde, such as sol- gel method, coprecip itation method, hydrothermal method, etc were briefly summarized. The investigation foreground in forming LiNbO₃ powder with uniform struc ture, high pure degree and small size paticles and its application was also introduced.
