Abstract
Ba 6-3x Nd 8+2x Ti 18 O 54 (BNT) is a useful dielectric resonator at microwave frequencies. Recent work has shown that the major secondary phase in this system can be indexed as Nd 4 Ti 9 O 24 (JCPDS 33-943). The present study has revealed that when half of the stoichiometric Ba +2 is replaced with Ca +2 or Sr +2 , a third, tilted perovskite-structured phase, NdTiO 3 , is also present. It forms as coherent intragranular regions within BNT grains and always contains some of the divalent dopant species. The orientational relationship between NdTiO 3 and BNT has been established.
