For biomedical applications, zirconia‐toughened alumina ceramics (see Figure) would be
very appropriate materials, provided that the zirconia content is kept below the percolation
threshold (upper limit of 16 vol.‐% 3Y‐TZP inside an alumina matrix). That the concept of a
percolation threshold is relevant when talking about aging degradation, is demonstrated by
comparing specular IR reflectance measurements with aging experiments.
