Synthesis of MgTiO3 by solid state reaction and characteristics with addition

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 °C possess excellent microwave dielectric properties: a dielectric constant er of 21, a τ f value of 0 ppm/°Cand a Q × f value of 130,000 GHz (at 13 GHz).
