The observation of the degradation of TiO2-based ceramic capacitors after hydrogen incorporation on the termination electrodes of the capacitors via electrolysis of water was presented. The Fourier-transform infrared (FTIR) absorption spectra analysis of polished rutile single crystals was also shown. It was found that the degradation exhibit a strong dependence on time at room temperature. It was proposed that hydrogen was metastable in TiO2and the hydrogen-induced degradation has different stabilities among various oxide-based components and devices.
