CR AU Coating Lithium Tantalate LiTaO3 Piezoelectric Effect
Crystals
Lithium tantalate (LiTaO3) is a perovskite which possesses unique
optical, piezoelectric and pyroelectric properties which make it
valuable for nonlinear optics, passive infrared sensorssuch as
motion detectors, terahertz generation and detection, surface
acoustic waveapplications, cell phones and possibly pyroelectric
nuclear fusion. Considerable information is available from
commercial sources about this salt.
Crystro's LiTaO3 lithium tantalate crystal has >99.99% purity. Find
high-quality lithium tantalate bulk crystals, wafers and substrates
