N2 - Sm2Zr2O7-SiO2 composite materials with different content and grain size of SiO2 was successfully prepared by optimized hot-pressing sintering process. The phase, microstructure and composition of the composite material were characterized by XRD, SEM and EDS. The dielectric properties were also investigated. The mechanism of dielectric properties was explored. The results were obtained as follows: Because of the reaction layer Sm2Si2O7 with relatively high dielectric constant, dielectric constant of the composite material increased as the SiO2 content inereasing.
