Piezoelectric LiNbO3 Substrate 128Y Cut With Orientation Flat Notch
Piezoelectric LiNbO3 Substrate 128Y Cut with Orientation Flat or Notch
Lithium Niobate (LiNbO3) is colorless transparent crystal. It belongs to tripartite system, the melting point is 1253°C, the density is 4.64 g/cm3, Mohs hardness is 5, refractive index no=2.286 ne=2.203 at 632.8nm. It is ferroelectric crystal, Curie point 1150°C. With lithium carbonate and niobium pentaoxide as raw materials, the crystal is grown in a platinum crucible by the lifting method. LiNbO3 is a kind of material with piezoelectric, ferroelectric, electro-optic, nonlinear optics, thermoelectricity and other properties. It can also be used as holographic recording medium material.
