Abstract: The low firing temperature glass-ceramics of B2O3-P2O5-MgO-Al2O3-SiO2 system were investigated. The dependence of heat-treatment on crystallizing phases and the properties of crystallizing phases were analyzed. This material with low dielectric constant and low loss tangent can be co-fired with Au, Ag/Pb, Cu paste under 1000℃, it can be a promising material for high frequency MLCIs.

Key words: high frequency chip inductors, low dielectric constant ceramic materials, low temperature-firing
