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
