Interdiffusion between Perovskite and Fluorite Oxides

Both perovskite and fluorite oxides can form solid solutions with the common oxide components allowing interdiffusion to take place. For example, manganese ions can diffuse from the perovskite to the fluorite oxide  

In this reaction, manganese ions are oxidised and oxygen is involved as a reactant. For the A-site-deficient Lai, .Mn03, the manganese solubility in YSZ increases. However, the manganese dissolution does not change the conduction characteristics very much [47],
