Percolative mechanism of aging in zirconia-containing ceramics for medical applications
Recently, several episodes of fracture of zirconia ceramic femoral heads of total hip prostheses have alarmed the medical and scientific community regarding aging problems in zirconia prostheses. Such fractures cause immediate local tissue reactions, which require urgent medical intervention to prevent further complications. Thus, an upper limit of yttria-stabilized zirconia (Y-TZP) concentration in alumina/Y-TZP composites was found to avoid future aging problems. This limit coincides with the percolation threshold measured by infrared (IR) reflectance in a series of alumina/Y-TZP composites.
