| ABSTRACT |
|
The compositions for LTCC embedded capacitors based on $BaTiO_3$ ceramics with $5~15;wt%$ of lithium-borosilicate glass frits were studied. After the glass frits, which is chemically stable and has acceptable ability of low-temperature sintering, were added to the host dielectric materials, the sintering behavior and dielectric properties were evaluated. As for $BaTiO_3$, relative density of >$95%$, permittivity 990, and dielectric loss $3.1%$ were obtained when sintered at $925^{circ}C$ with 5 wt$%$ of glass frits. As for $(Ba,Ca)(Ti,Zr)O_3$ ceramics, relative density of >$95%$, open porosity <$0.5%$, permittivity 700, and dielectric loss $2%$ were obtained when sintered at $875^{circ}C$ with 10 wt$%$ of glass frits. |
