摘要

The effects of additive sintering aids on the microstructures and microwave dielectric properties of 0.8(Mg0.95Zn0.05)TiO3-0.2Ca0.61Nd0.26TiO3 ceramics were investigated. V2O5 was selected as a liquid phase sintering aid to lower the sintering temperature of 0.8(Mg0.95Zn0.05)TiO3-0.2Ca0.61Nd0.26TiO3 ceramics. With added V2O5, the densification temperature of 0.8(Mg0.95Zn0.05)TiO3-0.2Ca0.61Nd0.26TiO3 can be effectively reduced from 1350 °C to 1175-1275 °C. Low-level doping of V2O5 (0.5-4 wt%) significantly improves the density and dielectric properties of 0.8(Mg0.95Zn0.05)TiO3-0.2Ca0.61Nd0.26TiO3 ceramics. The quality factor Q × f was strongly dependent upon the amount of additives. Q × f values of 46,100 and 14,700 GHz could be obtained at 1175-1275 °C with 0.5 and 4 wt% V2O5 added, respectively. Over all ranges of addition, the relative dielectric constants differed significantly and ranged from 20.6 to 26.5. The temperature coefficient varied from -14.9 to 8.91 ppm/ °C.
