Bioceramics are a class of ceramic materials designed for medical applications, particularly in the field of biomaterials. They are used to replace or repair damaged tissues and bones due to their biocompatibility, which means they can interact safely with biological systems. Common types of bioceramics include hydroxyapatite and calcium phosphate, which mimic the mineral component of natural bone. These materials can be used in various forms, such as coatings for implants or as scaffolds for tissue engineering. Bioceramics are favored for their mechanical strength, durability, and ability to promote osseointegration, the process by which bone attaches to the surface of an implant.
