Description

technical field [0001] The invention belongs to the field of biological materials, and in particular relates to a rare earth-doped bioactive glass ceramic and a preparation method of the biological ceramic. Background technique [0002] Bioceramic materials as biomedical materials began in the early 18th century. Up to now, a variety of bioceramic materials have been applied to the field of biomedicine. [0003] The composition of bio-glass ceramics contains more calcium and phosphorus than ordinary window glass, and it can chemically bond naturally and firmly with bone. Bioglass-ceramics have unique properties that distinguish them from other biomaterials in that a series of surface reactions rapidly occur at the implant site, eventually leading to the formation of a carbonate-based apatite layer. Bio-glass ceramics have good biocompatibility, the material is implanted in the body, there is no reaction such as rejection, inflammation and tissue necrosis, and it can form os...
