摘要：

The effects of zinc borosilicate addition (denoted as ZBS) on densification and dielectric properties of a binary composite of Zn2SiO4-CaTiO3 (denoted as ZSCT) ceramics have been investigated as a function of ZBS content and sintering temperature. Densities of the specimens were enhanced with an increase of ZBS and then decreased. High-density ZSCT + 20.0 wt% ZBS sintered at 925 degrees C showed promising microwave dielectric properties: relative dielectric constant (epsilon(r)) = 7, quality factor (Q x f) = 19,265 GHz at 15.5 GHz, and temperature coefficient of resonant frequency (tau(f)) = -21 ppm/degrees C, which demonstrated a potential candidate for application of low temperature co-fired ceramics field in millimeters and THz range.
