Coulometric Titration

With Coulometric titration the composition of a material sample is continuously changed and the potential profile of the electromotive force (EMF) is determined. Using EMF the thermodynamic data of the material can be calculated and from this the properties and phase diagrams of the material can be derived.

Within this method the construction of a galvanic cell is used to "titrate" ions by means of a current flow. By these ions, the composition of the starting material is intentionally changed and the EMF of the resulting alloy determined. From this potential other thermodynamic data can be calculated by the Nernst equation.
