Influence of annealing at intermediate temperature on oxygen transport kinetics of Pr2NiO4+δ
Electrical conductivity relaxation (ECR) and oxygen permeation measurements were conducted, at 750 °C, to assess the long-term oxygen transport characteristics of the mixed ionic-electronic conducting Pr 2 NiO 4+ δ with a K 2 NiF 4 structure. The results show that the apparent values for the oxygen...
