Effects of Al_2O_3 on the Microwave Dielectric Properties of MgTiO_3Ceramics
Source abstract
Abstract
MgTiO3 ceramics were prepared by MgO and TiO2 with A12O3 added, the sintering, microwave dielectric properties and phases were investigated. XRD shows that there are two phases in MgTiO3 ceramics without A12O3 added: MgTiO3 phase and MgTi2O5 phase; besides these phases, MgAl2O4 phase appears after Al2O3 added, because of the solid phase reaction between MgO and TiO2. Although the MgAl2O4 phase impedes sintering and decreases the density, it decrease the the dielectric constant and the dielectric loss.
