Abstract
The effects of alumine borosilicate glass composition on the densification and the microwave properties of (M $g_{0.93}$C $a_{0.07}$)Ti $O_3$ ceramics were studied. As the amount of glass increase, the density of ceramics increases and grain growth enhances. When 20 ~30 wt% of glass added, it was densified to over 95% of (M $g_{0.93}$C $a_{0.07}$)Ti $O_3$ theoretical density. (M $g_{0.93}$C $a_{0.07}$)Ti $O_3$ ceramic sintered at 95$0^{\circ}C$ exhibits dielectric constants of 15~16, quality factor of 8000 and temperature coefficient of resonant frequency of -45 ppm/$^{\circ}C$ by adding 20 wt% alumine borosilicate glass.
