In recent years, a family of high performance piezoelectric materials for general and specialized applications was developed: PZT-43, PZT-46, PZT-47, PZT-48, PZT-50, all of them exhibit high dielectric, piezoelectric, and elastic characteristics. A specialized piezoceramic material NPZT-2 having d33 = 800 pC/N , ε33 Т /ε0 = 4600, ТС= 140 °С and exhibiting low sintering temperature was developed.Unique piezoceramic material TCVC-2 with d33 = 340 pC/N, d15 = 520 pC/N was developed, its working temperature equals 320°С. JSC Research Institute "Elpa" is the only Russian research and production company, owning piezoelectric film casting technology and having the full manufacturing cycle for multilayer piezoceramic actuators and sensors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
