Dielectric Properties of Li₂MgTiO₄ Ceramic System at Microwave Frequency

Abstract:

The rock-salt structure Li2MgTiO4 ceramics were prepared by reaction sintering method and its microwave dielectric properties were investigated. The crystal structure and microstructure were analyzed using X-ray diffraction and scanning electron microscopy techniques. XRD showed that main phase Li2MgTiO4 combined with minor second phase Mg2TiO4 were formed after 1250-1350 oC sintering. The microwave dielectric properties of Li2MgTiO4 ceramics exhibited a significant depend on the density and to some extent on the morphology of the grains. Li2MgTiO4 sintered at 1325 oC/5h exhibits microwave dielectric properties of εr=13.2, Q×f=44 711 GHz (at 9.9 GHz ) and τf=-31ppm/oC.
