概要 |
Electrical resistivity (ρ) of Alkali-Silicate glasses has been measured to find out the behavior of Fe-ion in these glasses. ρ depends mainly upon the Fe^<2+>/Fe total-ratio, and has the minimum peak.... The behavior of Fe-ion at the minimum of ρ is discussed by the results of Mo^^¨ssbauer-spectra in terms of the oxygen-coordination number of Fe^<3+>-ion. The mechanism of electrical conductance in these glasses is assumed to be the valence electron transfer between Fe^<2+> and 6-fold oxygen Fe^<3+>.続きを見る
