Effect of composition of BaO·(R2O3)y·(TiO2) z·0.06(2Bi2O3·3TiO2) materials, R=Nd(1-x)Sm(x), BRT, on the materials characteristics and microwave dielectric properties of the samples was systematically examined. The Ti/Ba ratio (z value) shows the most significant effect on the microwave dielectric properties of the materials. The Q×f-value is small for z≦3.82 materials, and showing maximum value for z=4.32 samples, then decrease for z=4.52 composition, which is possibly due to the presence of secondary phase for z=3.82 and 4.52 materials. Diffusion couple experiments shows that the interaction diffusion zone between glass and BRT ceramic is not pronounced, so that Ba-B-Si glass and BRT could be a good low temperature co-firable ceramic system is inferable.
