Description

The 1:2 ordering in Ba(Ni1/3Nb2/3)O3 ceramics sintered at 1,350--1,500 C has been investigated by using XRD and Raman spectroscopy. Both of the techniques show that the degree of the 1:2 ordering decreases as the sintering temperature increases. However, XRD discerns the 1:2 ordering only for the samples sintered at 1,350--1,400 C, whereas Raman spectroscopy discerns the 1:2 ordering for all the samples. Similar results have been obtained for Ba(Zn1/3Nb2/3)O3 ceramics, where only the temperature range is slightly different. It is demonstrated that Raman spectroscopy can be a useful tool for probing of the 1:2 ordering in the A(B1/3'IIB2/3 double-prime V)O3-type complex perovskite compounds
