| Abstract: | (Ba0.6Sr0.4)TiO3-MgO composite ceramics were fabricated by a standard ceramics processing.Effect of the sintering temperature and time on sintering properties,microstructure and dielectric properties of samples were systemically studied.The results show that the radial shrinkage and the bulk density of the samples reached the maximum when the sintering temperature and time were 1550℃ and 3h,respectively.In addition,we obtained the biggest dielectric constant,the biggest tunability and the lowest dielectric loss of composite ceramics under above sintering conditions. |
