Single crystals of Lithium tantalate are pulled from the melt using the Czochralski method.

[2] Lithium tantalate is used for nonlinear optics, passive infrared sensors such as motion detectors, terahertz generation and detection, surface acoustic wave applications, cell phones.

Lithium tantalate is a standard detector element in infrared spectrophotometers.

[3] The phenomenon of pyroelectric fusion has been demonstrated using a lithium tantalate crystal producing a large enough charge to generate and accelerate a beam of deuterium nuclei into a deuterated target resulting in the production of a small flux of helium-3 and neutrons through nuclear fusion without extreme heat or pressure.

[4] A difference between positively and negatively charged parts of pyroelectric LiTaO3 crystals was observed when water freezes to them.
