Lithium tantalate crystal belongs trigonal crystal system and is a kind of distorted perovskite structure crystals. The dielectric constant is 41~53, the primary electro-optical coefficient ɣ12=7.0×10^-12m/V, and the electromechanical coupling coefficient R15≥0.3. LiTaO3 crystal is a ferroelectric crystal with Curie point (603±2)℃ and spontaneous polarization intensity 50×10^-6C/cm^2. Lithium tantalate crystal (LiTaO3) has excellent electro-optical, piezoelectric, electrical and pyroelectric properties, with a pyroelectric coefficient of 2.3×10-7 C/cm2/K. Lithium tantalate crystals also haas good mechanical and physical properties, and it is low cost. Lithium tantalate crystal is used as a Q-switch in laser technology, as a pyroelectric detector in infrared technology, and as a filter and resonator in the electronics industry.

Hangzhou Shalom EO offers the stocked and custom LiTaO3 crystals,wafers and substrates, the LiTaO3 crystals ingot and blanks are also provided. Advanced facilities are equipped for crystals growing, wafer cutting, lapping, polishing and checking under control of  ISO9001 managing system.
