Concentrated solar energy used for sintering magnesium titanates for electronic applications

•Different ratios of MgO/TiO2 ceramics were prepared by solid state reaction technique.•The compositions were (MgO)0.63(TiO2)0.37, (MgO)0.49(TiO2)0.51, (MgO)0.50(TiO2)0.50.•We sintered (MgO)0.63(TiO2)0.37, (MgO)0.49(TiO2)0.51, (MgO)0.50(TiO2)0.50 ceramics in air at about 1100°C in the solar furnace.•The structure, microstructure and dielectric properties of the solar sintered samples were studies and is presented.
