Abstract
High purity Nd2O3-doped (1−x)BaTiO3-xBi0.5(Na, K)0.5TiO3 (x = 0.00-0.08) were synthesized by a composite-hydroxide-mediated approach at 200°C using a hydrothermal reaction apparatus with a rolling system. The powders with an average size of 100 nm in diameter were produced and were sintered to almost full theoretical density at low temperature such as 1200°C for 2 h. Although (1−-x)BaTiO3-xBi0.5(Na, K)0.5TiO3 could not be poled, Nd2O3 additive was useful to proceed the polarization of (1−x)BaTiO3-xBi0.5(Na, K)0.5TiO3 ceramics.
