Low dielectric constant composites based on B2O3 and SiO2 rich glasses, cordierite and mullite
Source abstract
Abstract
Abstract The paper reports on sintering and dielectric properties of several glass-ceramic composites based on B2O3 and SiO2 rich glasses, cordierite and mullite. The dielectric constant values for the developed composites are low, in the range of 4.8–6.7 at 1 MHz. Some of the investigated materials exhibit low sintering temperature, suitable for LTCC (low temperature cofired ceramics) technology. A selected composite characterized by a low sintering temperature of 920 °C, low dielectric constant of 4.7 at 1 THz, thermal expansion coefficient well fitted to silicon and compatibility with commercial thick film conductive pastes was used for preparation of green tapes destined for LTCC microwave substrates.
