Tape casting and dielectric properties of SiO2-filled glass composite ceramic with an ultra-low sintering temperature

The tape casting and the dielectric properties of the suitability of dielectric ceramics made of silicon dioxide-filled zinc borate glass with an ultra-low sintering temperature (650 °C) were investigated. The effects of the dispersion, the binder and the plasticizer amounts on the slurry were found to obtain an optimum composition for tape casting. The sintering temperature dependence on dielectric properties of the tape was reported. In addition, electrodes on a multilayer module made on laminated tapes were prepared using Ag paste and post-firing, followed by scanning electronic microscope to verify the chemical compatibility under the co-firing process. The results show that the composition is well suitable for the tape process for low temperature co-fired ceramic technology.
