Product Description:

1, lithium tantalate is a chemical substance, chemical formula LiTaO3. Colorless or yellowish crystal. Tripartite system, distorted perovskite type structure, point group C63vR3C. Density 7.49g/cm3. Mohs hardness 5.5 ~ 6.0. Refractive index nD=2.176. Dielectric constant 41 ~ 53. Primary electro-optic coefficient r12=7.0×10-12m/V, electromechanical coupling coefficient R15≥0.3. Is ferroelectric crystal, Curie point (665±5)℃, spontaneous polarization intensity 50×10-6C/cm2. With excellent electro-optic, voltage, electric, pyroelectric properties, pyroelectric coefficient of 2.3×10-7 C/cm2/K. Grow by lifting method. It is used as Q-switch in laser technology, pyroelectric detector in infrared technology, and filter and resonator in electronics industry.

2. Surface acoustic wave level LT crystals are used to make wafers, and IDT lines are designed above wafers to form functional devices for acoustic transmission, which are widely used in the communication industry.
