抄録

Titanium seems to be suitable for use as anode material of an electrolytic capacitors because of its higher corrosion resistivity than aluminium, its lower cost than tantalum, and the very large dielectric constant of its oxide. However, it is of no practical use due to its appreciable leakage current. An electrolytic capacitor with a titanium-plated aluminium electrode was compared with that with an ordinary aluminium electrode. It was found that the leakage current and the power factor increased, while the increase in capacitance was very small. The large leakage current is characteristic of the oxide film of titanium and is not due to the impurities in titanium. Therefore, inspite of the several excellent properties of titanium for the electrolytic capacitor, the realization of its practical use is a remote possibility.
