Abstract

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 ΔH_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.

硅的隐晶形式的电导率

摘要

已经研究了外源性硅化物的天然样品的电导率。在515-700 K的温度范围内，电导率从1.1×10 ^-7增加到1.3×10 ^-6 S / cm，而电转移的激活焓为ΔH _a = 0.48±0.04 eV。显然，电导率是由质子在硅化物的毛细管通道中存在的水溶液中的质子迁移（根据格罗索斯机制）引起的。
