| ABSTRACT |
|
The effect of glass addition on the low-temperature sintering and microwave dielectric properties in $BaO-Nd_2O_3-TiO_2$ dielectric ceramics were studied. When 10~30 wt% of alkali lithium borosilicate glass was added, the sintering temperature decreases from $1300^{circ}C$;to;1000^{circ}C$ and the relative density more than 95% was obtained. When the added amount of glass increased above 10 wt%, the density as well as dielectric properties changed, which was attributed to the second phase formation. When the sample was sintered at 100$0^{circ}C$ with l0wt% of glass, the dielectric properties of $Qxf_o{ge}2800,;{varepsilon}_r{ge}65;and;{ au_f=+55 ppm/^{circ}C$ were obtained. 저 ꢕ잖⨀ ꂕ잖⨀ 梓 |
