| Abstract: | When 1.5 wt% of Li2O–B2O3–SiO2 and 1.5 wt% of Li2O–B2O3–Al2O3 glass‐added (Ca0.7Sr0.3O)1.03(Ti0.1Zr0.9)O2 batch was ball milled for 10~30 h followed by sintering at 950°C in flowing N2‐10%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. |
