Iridium-loaded titanium oxide (Ir − IrO2/TiO2) particles with unique structures have a potential to become an outstanding highly conductive material for various applications. In this paper, we investigated the effectiveness of annealing treatment of flame-made Ir − IrO2/TiO2 particles to enhance its electrical conductivity. Before annealing treatment, the Ir − IrO2 species was amorphous even though the Ir − IrO2 species uniformly covered the TiO2 surface. After annealing treatment at temperature of 750 °C, the phase of IrO2 changed from amorphous to crystalline phase, and the degree of crystallinity of IrO2 increased. The electrical conductivity of the Ir − IrO2/TiO2 particles increased from 1.05 S.cm−1 to 1.85 S.cm−1 with increasing annealing temperature from before annealing to 750 °C, which demonstrates the improvement of the crystallinity of Ir − IrO2/TiO2 particles after annealing treatments.
