摘要：
Effects of V2O5 addition on the microwave dielectric properties of 16CaO-9Li(2)O-12Sm(2)O(3)-63TiO(2) (abbreviated CLST) ceramics prepared by conventional mixed oxides method were investigated as a function of V2O5 content and sintering temperature. All the specimens were sintered between 1100 degrees C and 1250 degrees C. The sintering temperature of the CLST ceramics was lowered by 100 degrees C with V2O5 addition. With the changing content of V2O5, the dielectric constants lie between 88.6 and 108.2, while the Qxf values are between 3275 and 6573 GHz. Especially, the specimens doped by 0.75 wt% V2O5 sintered at 1200 C and 1250 degrees C for 3 h show good microwave dielectric properties with Kr=100.4-108.2, Qxf>4500GHz, and TCF=7-8 ppm/degrees C. Obviously, V2O5 could be used as a suitable sintering aid that could improve densification and microwave dielectric properties of the CLST ceramics.
