Electrochemical measurement of solubility product of metal oxides in liquid metals by coulometric titration of oxygen
نویسندگان
چکیده
We propose a new electrochemical method for the measurement of solubility product oxide metal impurity, in liquid solvent that is less easily oxidized than impurity. When known amount oxygen continuously added into by coulometric titration, dissolved impurity reacts with oxygen, forming oxide. By measuring concentration during can be derived. From this product, using thermochemical data chemical species involved oxidation reaction, i.e. Sieverts’ constant and Gibbs free energy formation oxide, elemental metallic element derived as well. In work, we validate magnetite (Fe 3 O 4 ) molten lead-bismuth eutectic alloy (LBE), temperature range 723–826 K.

Determination of Oxygen Nonstoichiometry and Diffusivily in Mixed Conducting Oxides by Oxygen Coulometric Titration I. Chemical Diffusion in La085r02CoO3_5
Oxygen coulometric titration has been applied to measure chemical diffusion in La0 45r0 2CoO36 between 700 and 1000°C. The transient current response to a potentiostatic step has been transformed from the time domain to the frequency domain. The equivalent circuit used to fit the resulting impedance data contains the element that describes the finite-length diffusion of oxygen into the sample s...
