摘要：
Conventional solid-state methods were used to synthesize Mg2SiO4 ceramic at relatively low sintering temperatures with the assistance of CaO-B2O3-SiO2 (CBS) glass. The effects of the CBS additions on the sintering behavior, crystal structures, microstructures, and microwave dielectric properties of Mg2SiO4 ceramic have been investigated in detail. The results indicate that the addition of CBS glass lowered the sintering temperature of Mg2SiO4 ceramic significantly. The Mg2SiO4 ceramic with 7 wt.% CBS addition sintered at 1325A degrees C for 4 h shows excellent microwave dielectric properties: epsilon (r) = 6.47, Q x f = 16,552 GHz, tau (f) = -23.34 ppm/A degrees C.
