Perovskite-type oxynitride, having oxide and nitride ions together in a compound, is a new class of dielectric material. Its dielectric property is related to the anionic configuration of short-range cis-type O/N ordering in crystal structure. Dielectric property including piezoelectric response was found out on its dense sintered ceramics. In this report, our recent studies on perovskite-type oxynitride dielectrics are reviewed with a characterization of crystal structure, development of sintering process and observation of a ferroelectric response in an oxynitride bulk ceramics.
