摘要：

CaMgSi2O6 (CMS) ceramics prepared by the solid-state ceramic route have a sintering temperature of 1300 degrees C/2 h. The sintering temperature of CMS was reduced below the melting point of Ag using low-melting LBS and LMZBS glasses. In the case of CMS + 15 wt% LMZBS sintered at 900 degrees C/2 h, the dielectric properties obtained were epsilon(r) = 8.2, Q(u) x f = 32,000 GHz (10.15 GHz), and tau(f) = -48 ppm/degrees C. The CMS + 15 wt% LBS composite, sintered at 925 degrees C/2 h, showed epsilon(r) = 8, Q(u) x f = 15,000 GHz (10.17 GHz), and tau(f) = -49 ppm/degrees C. The chemical compatibility of Ag with the ceramic-glass composites was also investigated for low-temperature co-fired ceramic applications.
