Abstract:Abstract:In this paper, Pb(Mn 1/3 Nb 2/3 ) 0.07 (Ni 1/3 Nb 2/3 ) 0.10 (Zr 0.5 Ti 0.5 ) 0.83 O 3 ceramics were fabricated by the conventional solid state method to obtain excellent dielectric properties for ultrasonic generators. The effects of 2nd calcination temperature on their microstructure and piezoelectric properties were systematically investigated. The tetragonality increased in the ceramics when 2nd calcination temperature increased to the optimized temperature at 750℃. At that temperature, excellent … Show more
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.
