Abstract
A TiO2–RuO2–IrO2–Ta2O5 anode coating, with a particle size of about 7 nm, on titanium was prepared by thermal decomposition at 500°C. The phase structure of the quaternary oxide coating was analyzed using X-ray diffraction. The microstructure of the coating was investigated using scanning electronic microscopy and high-resolution transmission electronic microscopy. The crystallite phases of the coating are rutile-type solid solutions, including the TiO2-based solid solution, (Ti, Ru, Ir)O2, as the major phase and the IrO2-based solid solution, (Ir, Ti, Ru)O2, as the minor phase. In addition, tantalum remains amorphous in the coating. The coating contains primary cracks and secondary cracks. Large amount of isometric crystallites exist in the coating. There are also some columnar crystallites of (Ir, Ti, Ru)O2 at the bottom of primary cracks.
