Abstract:
    MgTiO<sub>3</sub>, MgTi<sub>2</sub>O<sub>5</sub> and Mg<sub>2</sub>TiO<sub>4</sub> were examined as DSC electrodes to improve photoelectric conversion efficiency. MgCO<sub>3</sub> (basic) and TiO<sub>2</sub> powders (nominally, Mg:Ti = 1:1, 1:2 and 2:1 in mole fraction) were wet-ball milled in ethanol for 24 h. The mixed powders were calcined in air at 1100 °C for 2 h to obtain the MgTiO<sub>3</sub> and MgTi<sub>2</sub>O<sub>5</sub> powders, and at 1300 °C for 2 h to obtain the Mg<sub>2</sub>TiO<sub>4 </sub>powder. Single-phase MgTiO<sub>3</sub>, MgTi<sub>2</sub>O<sub>5</sub> and Mg<sub>2</sub>TiO<sub>4</sub> powders were successfully synthesized. Although the DSC performance was not as high as expected, all samples were functioned as DSC.
