Abstract

The ordering behaviour of Ba(Mg_1/3Nb_2/3)O₃ ceramics (BMN) substituted by La³⁺, Na⁺, K⁺ was investigated using X-ray powder diffraction and transmission electron microscopy. The 1:2 ordered structure of BMN can be transformed to 1:1 ordered structure by substituting a small amount of La cation ion into the A-site. Moreover, the degree of ordering was increased with La content in the compound, and reached almost unity at [La] = 50 mol%. When the La ion in (Ba_1-xLa_x)(Mg_(1+x)/3Nb_(2-x)/3)O₃ (BLMN) was substituted by Na or K ions, the 1:1 ordered structure of BLMN was transformed into the 1:2 ordered structure. The degree of 1:2 ordering was influenced by the sintering temperature and the size difference between the A and B site ions.
