Sodium Chloride Electrolyte Data at High Temperatures and Pressures

Abstract

Electrolyte conductivities were measured and ion mobilities were calculated for use in applying the theoretical model for high rate Electrochemical Machining which was described in two other papers. The ions treated are Na+, Cl−, Fe++, and OH−. Mathematical models are derived to allow simple calculation of ion mobilities including the case where mixtures of ions are present. The effect of high temperatures (on the order of 200 deg C) and high pressures (on the order of 220 bars) is emphasized. The experimental apparatus used in making these measurements is also described.
