Abstract: A low-temperature co-fired composition with sintering temperature of <900 °C was developed using rare earth derived borate glass (La₂O₃-B₂O₃-TiO₂) and a conventional BNT (BaONd₂O₃-TiO₂) ceramic. The sintering behavior, phase evaluation, sintered morphology, and microwave dielectric properties were investigated. It was found that increasing the sintering temperature from 750 to 850°C leads to increases in shrinkage, densities and microwave dielectric properties (≈ 20 for ε_r and >8000 for Q*f₀). However, after 850 °C , the values of these properties decreased. It is suggested therefore that this new composite has good potential as a new candidate for low temperature co-fired ceramic (LTCC) materials.
