Lithium Tantalate (LiTaO3) Wafers are a type of single-crystal substrate used in electronics and optoelectronics applications. They are made of a compound consisting of lithium, tantalum, and oxygen atoms arranged in a crystal lattice structure.
LiTaO3 wafers exhibit piezoelectric and pyroelectric properties, making them useful in various devices such as surface acoustic wave (SAW) filters, sensors, actuators, and frequency control components. Their piezoelectric properties enable LiTaO3 wafers to convert mechanical vibrations into electrical signals or vice versa, while their pyroelectric properties allow them to generate an electrical voltage in response to temperature changes.
Lithium Tantalate Wafers are typically cut and polished into various sizes and orientations depending on the specific application requirements. They are available in different thicknesses and can be purchased as bare wafers or with specific thin film coatings applied on their surfaces.
