摘要： 采用微晶玻璃工艺,制备出一种ZnO-Li2O-B2O3-SiO2系陶瓷材料.该体系材料可在900℃空气气氛中烧结.烧结体的介电常数低于4,介电损耗为1.3×10-3.该烧结体中的晶相主要为圆球状和长柱状的Zn2SiO4,以及块状的SiO2.该材料适用于超高频多层片式电感领域.

关键词: 低烧结温度, 低介电常数和损耗, 高频MLCI

Abstract: Low dielectric constant and loss glass ceramics were synthesized from ZnO-Li2O-B2O3-SiO2 system. The low dielectric glass ceramics can be sintered below 900℃ in air. The typical dielectric properties of the glass ceramics are: dielectric constant <4, dielectric loss < 1.5×10-3 at the frequency of 1MHz. The glass ceramics are promising as dielectric material in super high frequency MLCIS.

Key words: low sintering temperature, low dielectric constant and loss, high frequency MLCI
