| Abstract: | The possibility to measure oxygen nonstoichiometry in oxides by two-electrode coulometric titration technique with a solid-electrolyte cell has been demonstrated. The P(O2)-T-S diagrams of praseodymium oxide and La0,3Sr0,7CoO3-5 solid solution, determined by the two-electrode technique, are in a good agreement with the literature data, obtained by thermogravimetry and coulometric titration in four electrode cell. The two-electrode titration technique makes possible to study relative nonstoichiometry of oxide materials in the temperature range 770-1220 K at oxygen activities from 10 "to 1. |
