Abstract
Ordered structures of Ba(Cd 1/3Ta 1/2)O 3 ceramics with and without boron additive were investigated systemically by electron diffraction and high resolution transmission electron microscopy. The results showed a well-ordered structure of 1:2 with hexagonal symmetry for Ba(Cd 1/3Ta 1/2)O 3 with boron additive. No significant changes in ordered structures were observed after long-period annealing. The 1:2 ordered domain structures (average domain size ∼ 18 nm) and high-density domain boundaries induced by ordering were observed for Ba(Cd 1/3Ta 1/2)O 3 without boron additive sintered at relatively high temperature. The sintering process has a profound influence on the microstructure of Ba(Cd 1/3Ta 2/3)O 3 ceramics.
