摘要：Niobium and tantalum-based ternary oxides have been found to be good candidates for electronicapplications because of their excellent dielectric properties.In earlier studies it was found that addition of frit glass improvesdensity, mechanical strength and dielectric properties of BMT hence, in the present study B2O3 was added to BMN, BZN,BMNT andBZNT. These samples were prepared by solid state route and the phase was confirmed by XRD. To thesesamples B2O3 was addedin varying weight percent (1 to 3%) and the pellets were sintered at 1250˚C. These samples weresubjected to capacitance and dielectric measurements. From the results it was observed that addition of frit glassincreasedthe density to some extent but did not improve capacitance and infact reduced the dielectric constant drastically of theceramics. Hence it is concluded that addition of B2O3 has detrimental effect on BMN, BZN, BMNT and BZNT.
