Ceramics are found in the family of calcium phosphates. Ex. Tricalcium phosphates, Hydroxyapatite, substitute apatite, biphasic system. They often have similar properties to the composition of bone. Their objective is to only mimic the mineral component of bone. They can also be considered bio-absorbable. They avoid the formation of fibrous tissue, and encapsulation of the implant, thus isolating it from the body system (this is a result of an immunological response). A lot of metal orthopedic implants are coated with this material, to help avoid this type of reaction.
Nonoxide ceramics
An example of this is silicon carbide. They have no sensitivity to fracture. They are also very chemically stable. They provide good resistance to high temperatures, as well as have good physical strength. They have good porosity to support new in growth of cells and will improve osteo-integration in the body. A lot of these ceramics are from wood derivatives, have often mimic the properties of plant vascular systems.
Pyrolytic Carbon
These are in the form of nanotubes and nanofibres. They have good overall composition, morphological traits, as well as strong physical and electrical properties.

Si C and Carbon scaffolds
A lot of these scaffolds derive from wood plants. They have a high potential to release cytoxic particles. All plant derived test subjects behave very similarly. Their vascular bundles have pores that will allow for vascularization to occur. They do not have any…
