PZT-5H has very high permittivity, coupling, and piezoelectric constant, but lower time stability. It is used in applications requiring fine movement control or for sensitive receivers. Its low Curie temperature restricts its operating temperature range. Applications include medical diagnostics, industrial NDT, STM/AFM, and nano-positioning.
