Abstract
The oxidation in air of black core in ceramic specimens formed by pres sing has been studied under experimental conditions in which the rare of oxygen diffusion through the oxidised layer was the late controllin g step in the oxidation process. An equation is proposed, which allows the value of the effective coefficient of oxygen diffusion through th e oxidised layer to be predicted fi om the propel ties characterising the layer's porous structure (porosity, tortuosity, and average pore r adius).
