Electrical conductivity of liquids

Furthermore, the electrical conductivities of liquid Na-Sn alloys for the five compositions are determined with the Kubo-Greenwood scheme, using the trajectories from our ab initio MD simulations. The calculated values reproduce the measured strong variation of the conductivity with the Na (or Sn) concentration very well. The small (semimetallic) conductivity of the alloys with nearly equimolar composition can be explained by the position of the Fermi energy between the occupied sp-band of tin and the sp-band of sodium.

As expected of a network liquid, the electrical conductivity of liquid B203 increases with increasing concentration of metal oxides. The specific conductivity of liquid alkali borates containing only 1 mole-% metal oxide is approximately ten times greater than that of pure B203 (47). Some typical conductance values of liquid borates are shown in Table VI. At...

I2CI+ Ion. There is no certain evidence for the I2C1+ cation 335, but presumably the electrical conductivity of liquid IC1 (specific conductance = 4.60 10-3 ohm-1 cm-1 at 35°C) which has previously been ascribed to the self-ionization829 according to Eq. (4.207) is in fact due to a self-ionization that produces I2C1+ ion 335 [Eq. (4.208)].

An investigation has been conducted on the electrical conductivities of liquid sulfur and some sulfur-phosphorus mixtures. The purpose of this work was (1) to obtain additional data on the conductivities of liquid semiconductors, which are of theoretical interest, and (2) to investigate the possibility of using these materials as the cathode reactant in lithium-chalcogen electrochemical cells. It is difficult to obtain reliable conductivity data on these systems because of their low conductivities, the strong influence of impurities on their conductivity, and corrosion problems associated with most electrode materials. 

The vapour pressure of V2O5 has been determined between 973 and 1473 K, and the enthalpy of evaporation calculated as ca. 143 kJ mol . The electrical conductivity of liquid V2O3 has been measured as a function of both temperature and partial pressure of oxygen. Raman and i.r. spectra or oriented single-crystals of V2O5 have been recorded and the absorption frequencies compared with those calculated using a simple transferred force-field. 2... 

The electrical conductivity of liquid hydrocarbons can be measured by a precision meter. The method is used to evaluate aviation fuels and oflier low-conductivity hydrocarbons. The generation and dissipation of electrostatic charges in liquids during handling depends on ionic species which may be characterized by electrical conductivity at rest. The dissipation time of the charges is inversely proportional to the conductivity. The measurement is done by a conductivity meter.
