Data bank on properties and applications of ferro-piezoelectric materials

Work on the formation of the data bank on FPCM developed at the Institute of Physics (Rostov State University) is under way. The bank contains electrophysical, elastic structural parameters of materials, their chemical composition and technological characteristics and the fields of applications. FPCM of different groups possess various parameters: very high and extremely low values of permittivity and mechanical quality, low dielectric losses; high values of piezoelectric response; temperature stability of resonance frequency and Curie point. There is a wide spectrum of FPCM applications: low- and high-frequency devices, high sensitive and high-temperature transducers, devices with high specific power, filter devices and others. The use of the data bank will make it possible to proceed to a new step of analyzing and generalizing the results of investigations of FPCM. The analytical dependences relating the composition of materials with their properties will allow one to predict and to design materials with prescribed properties.
