| Abstract: | In this paper,the propagating velocities of bulk acoustic waves(BAW) in new-type piezoelectric crystal Ca3NbGa3Si2O14(CNGS) were calculated along the x,y,and z axes.The slowness curves of propagating velocities in yz,xy and xz planes were plotted.Some theoretical guidance for piezoelectric device design as well as its application of CNGS crystal can be provided by these results. |
