摘要：

Magnesium titanate was synthesized by the solid state reaction. Powder XRD method was used to identify the phases and content, which indicates that pure phase of MgTiO3 can be synthesized by the solid state reaction even without the addition of excess MgO. Doped with 5 at.% CaTiO3 and 6 wt.% ZnNb2O6, MgTiO3 ceramics sintered at 1300 degrees C possess excellent microwave dielectric properties: a dielectric constant epsilon(r) of 21, a tau(f) value of 0 ppm/degrees C and a Q x f value of 130,000 GHz (at 13 GHz).
