Abstract

New microwave materials based on a gadolinium zinc borate (20ZnO-20Gd ₂O₃-60B₂O₃) glass with typical Al₂O₃ filler have been investigated as a dielectric candidate for low temperature co-fired ceramic (LTCC) applications. The experimental parameters, such as filler contents and firing temperature, were found to affect seriously densification, crystallization and microwave dielectric properties. The presence of ZnAl₂O₄ and GdBO₃ phases with an unexpected GdAl₃(BO₃) ₄ phase were assumed to influence the final performance of the materials. In particular, the GdAl₃(BO₃)₄ phase is the consequence of chemical reactions between the glass and Al ₂O₃ filler during firing. As a promising dielectric composition, the sample consisting of 20ZnO-20Gd₂O ₃-60B₂O₃ and 40 wt.% Al₂O ₃ filler exhibited k (dielectric constant) ∼8.1 and Q (quality factor) ∼ 312 at 18.6 GHz when fired at 850°C.
