Lithium niobate (LiNbO3)

Lithium niobate (LiNbO3)

Снимок.PNGLithium niobate (LiNbO3– is one of the piezoelectric crystals. One of the important properties of this crystal is the high speed of propagation of the surface wave, which depends on the plane of the slice. It is thanks to him that it becomes possible to use lithium niobate for broadband devices.
