摘要： 采用传统的电子陶瓷生产工艺，制备出一种Ｂ２Ｏ３－Ｐ２Ｏ５－ＳｉＯ２系瓷料．该体系材料加入少量助烧剂可在９００℃，空气气氛中烧结，获得低介电常数陶瓷．得到烧结体的介电常数ε≤５、介电损耗ｔａｎδ≤３×１０－３（１ＭＨｚ）；有望用于超高频叠层片式电感领域．

关键词: 低介电常数, 低烧结温度, 片式电感

Abstract: A novel B2O3-P2O5-SiO2 ceramic was synthesized by the conventional mixed-solid method using PbF2 as a low melting point additive. The low dielectric ceramic can be sintered below 900℃ in air. The typical dielectric properties of the sintered ceramics derived from the mixed-solid method show as: dielectric constants below 5, and dielectric loss less than 3×10-3 at the frequency of 1MHz. The ceramics are potential for using as dielectric material in super high frequency multi-layer chip inductors.

Key words: low dielectric constant, low sintering temperature, multi-layer chip inductors
