MEDICAL CERAMIC MATERIAL AND MANUFACTURING METHOD THEREOF
The present invention provides a medical ceramic material with a color other than black or white, especially blue, with which it is possible to secure sufficient durability and to maintain a good appearance by sufficiently suppressing a color difference between before and after the irradiation of gamma-rays for sterilization. The medical ceramic material is formed using a composite material containing alumina and zirconia. The composite material contains cobalt oxide. The content of cobalt oxide is set to be 0.2 wt% to 1.0 wt% with respect to 100 wt% of the composite material excluding cobalt oxide.
