Lithium Niobium Trioxide Lithium Tantalate Crystals Lithium Niobate LT LN Crystals For 5G
Lithium niobate crystal is one of the most widely used new inorganic materials, it is a good piezoelectric energy exchange material, ferroelectric material, electro-optical material, lithium niobate as electro-optical material in optical communication to play the role of light modulation. Its single crystals are important materials for optical waveguides, mobile phones, piezoelectric sensors, optical modulators and a variety of other linear and nonlinear optical applications.
Lithium niobate was prepared using lithium carbonate and niobium pentoxide as raw materials by pulling method: lithium carbonate and niobium pentoxide were put into a platinum crucible and crystals were grown along the direction (001). In order to obtain high quality colorless transparent cylinder, it is necessary to add an appropriate size of electric field when the temperature of the two end faces in the two directions of crystal growth is slightly higher than the Curie temperature, and then form the crystal to cool the crystal to room temperature, that is, to prepare lithium niobate crystal.
