State-Of-The-ART Review on Ferroelectric Ceramic Materials

摘要

The report presents a survey of ceramic systems exhibiting ferroelectricity together with fundamental data on ferroelectric crystals. A review of the basic reasons for the occurrence of ferroelectricity as well as for the dependence of the ferroelectric transitions and the properties of ferroelectric materials on the intensive parameters follows. The dielectric, piezoelectric and elastic properties of experimental and commercially available ceramic feffoelectrics are listed. The interpretation of dielectric properties of ceramic ferroelectrics as modified single-crystal properties includes a discussion of dielectric constant, stability, nonlinear behavior and domain effects. Techniques for poling and special forming methods for ferroelectrics are described followed by a discussion of the linear and non-linear devices employing ferroelectric materials. (Author)
