Abstract

When 1.5 wt% of Li₂O-B₂O₃-SiO₂ and 1.5 wt% of Li₂O-B₂O₃-Al₂O ₃ glass-added (Ca_0.7Sr_0.3O) _1.03(Ti_0.1Zr_0.9)O₂ batch was ball milled for 10~30 h followed by sintering at 950°C in flowing N ₂-10%H₂ atmosphere, an apparent density of approximately 4.5 g/cm³, a dielectric constant of approximately 26, and a quality factor of roughly about 3300 GHz were demonstrated. A prolonged ball mill time thereafter significantly decreased both of the dielectric properties because of the enhanced reduction of the specimens during sintering. The apparent evidence of a material reaction between the dielectric material and the copper electrode was not observed.
