Application of La2O3-B2O3-TiO2 Glass-Ceramic for Low Temperature Co-Fired Ceramic (LTCC) Materials
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 εr 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.
