Beschreibungen/Notizen

• The electrical conductivity of natural samples of exogenous silicides has been studied. In the temperature range of 515−700 K, the conductivity increases from 1.1 × 10 −7 to 1.3 × 10 −6 S/cm, while the activation enthalpy of electrical transfer amounts to Δ H a = 0.48 ± 0.04 eV. Apparently, the electrical conductivity is caused by the migration of protons (according to the Grotthuss mechanism) in the aqueous solution present in capillary channels of silicides.
