Effect of Sb2O5 addition on phase formation and characterization of (Bi1/2Na1/2)TiO3-(K 1/2Na1/2)NbO3 ceramics
In this study, Sb2O5 doped (Bi0.5Na0.5)TiO3-(K0.5Na0.5)NbO3 ceramics have been prepared by a conventional mixed-oxide method via vibro-milling technique. The phase formation behavior, microstructure and electrical properties have been investigated as a function of Sb2O5 content. It is shown that the...
