The qualities and parameters of the special piezoelectric crystals, which have specific directions were compared, and then the specific directions of LiGaO2 and BaTiO3 were calculated and proved.
In the beginning of this paper, background of ferroelectrics, main research methods of ferroelectric film, research status of ferroelectric film and BaTiO3 crystal phase transition are introduced.
