Abstract

Rare earth elements are widely used in metallurgy for alloying. It is known that small admixtures of these elements give unique properties to alloys. Rare earth oxides are used, for example, in optics or in solid-oxide fuel cells. In this work, the properties of electrodes based on oxides of titanium, ruthenium and rare earth oxides are investigated. The effect of organic additives on the surface properties of the electrode has also been studied. In the sample with butanol, the current density in the sodium chloride solution is almost 10 times higher than that of the electrodes without butanol. For the samples that showed the best results in electrochemical tests, the surface morphology was explored. The surface microphotographs demonstrate the cracks and the inclusions of rare earth oxides.
