Abstract

The Sr2ZnSi2O7 ceramics sintered at 1475°C has ɛr=8.5, Qu×f=105,000 GHz (at 12.63 GHz), and τf=−51.5 ppm/°C. The sintering temperature of Sr2ZnSi2O7 has been lowered to 875°C by the addition of 20Li2O–20MgO–20ZnO–20B2O3–20SiO2 (LMZBS) glass. Addition of a small amount of SrTiO3 lowered the value of τf. Tapes were cast using the composition Sr2ZnSi2O7+15 wt% LMZBS. The stacked and sintered tapes exhibited ɛr∼7 and tan δ∼10−3 at 290 K. The chemical compatibility of Ag with the ceramic–glass composites was also investigated.
