Sintering and Dielectric Properties of Li 2 O – B 2 O 3 – Al 2 O 3 – SiO 2 Glass‐Added ( Ca 0.7 Sr 0.3 O ) 1.03 ( Ti 0.1 Zr 0.9 ) O 2 for Copper Electrode

Abstract
When 1.5 wt% of Li 2 O – B 2 O 3 – SiO 2 and 1.5 wt% of Li 2 O – B 2 O 3 – Al 2 O 3 glass‐added ( Ca 0.7 Sr 0.3 O ) 1.03 ( Ti 0.1 Zr 0.9 ) O 2 batch was ball milled for 10~30 h followed by sintering at 950°C in flowing N 2 ‐10% H 2 atmosphere, an apparent density of approximately 4.5 g/cm 3 , 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.
