The role of the La-addition on the A-site of the perovskite Pb(Mg 1/3 Nb 2/3 )O 3 (PMN) on the phase formation, microstructure and dielectric properties was investigated. Ceramic samples were obtained from PMN and (Pb 1-x La x )(Mg 1+x/3 Nb 2-x/3 )O 3 (PLMN) nanopowders synthesized by the columbite
Pb(Mg 1/3 Nb 2/3 )O 3 ceramics prepared via columbite method exhibit high crystallinity and high density after sintering at 1200 β’ C. Typical relaxor behavior are demonstrated by the dielectric data. Although showing a diffuse phase transition, at room temperature the system is in its paraelectric s
In this paper, Pb(Zr,Ti)O 3 -Pb(Zn 1/3 Nb 2/3 )O 3 -Pb(Sn 1/3 Nb 2/3 )O 3 -Pb(Mn 1/3 Sb 2/3 )O 3 (named briefly PZT-PZN-PSN-PMS) quinary system piezoelectric ceramics with various Zr/Ti ratio were prepared by traditional method. The properties of this quinary system piezoelectric ceramics were studi
