dc.description.abstractPerovskite related dielectric oxides of the formula Ba(Zn1=3Nb2=3)O3, Ba(Mg1=3Nb2=3)O3 and Ba(Zn1=3Ta2=3)O3 have been synthesized by the NaCl–KCl molten salt (flux) method at low temperatures of 900-C for 3 or 6 h. Sintering at 1000-C retained the cubic structure.Sintering at 1300-C generated minor amount (-10%) of Ba5Nb4O15 in addition to the main cubic phase for the niobium compounds.The tantalum compounds, on the other hand, decomposed to Ba0:5TaO3, retaining a minor amount of the original cubic phase. Scanning electron micrographs show large grain size (upto 10mm) in some of the samples obtained by the molten salt method.en
