英文摘要	PZT95/5 ferroelectric ceramics are widely utilized in pulsed power devices and the remanent polarization Prof poled PZT95/5 can characterize the shock-driven energy density. However, this remanent polarization is difficult to be measured nondestructively. In this article, a series of pyroelectric tests of poled PZT95/5 ceramics were conducted near room temperature, from 25°C to 20°C. A linear relation between Prand pyroelectric coefficient p was found, that is, Pr=1190.5(K)×p, which provides an effective way to nondestructively estimate the value of Prof the poled PZT95/5 ceramics by measuring the pyroelectric coefficient p at room temperature. According to Devonshire's phenomenological theory, this result could be explained by a modified equation: p/r, where r=αPr/c represents the relative dielectric constant, C represents the Curie constant, and α (equals to 0.52 for PZT95/5 ceramics) represents a modification factor for ceramics, respectively. © 2017 The American Ceramic Society
