Effects of the addition of boron – nitride nanoplatelets to hydroxyapatite : processing, testing, and characterization
MetadataShow full item record
Bioceramics range in biocompatibility from inert oxides that do not react with the body to the other extreme of materials that completely absorbed by the human body, but are prone to failure by fracture. Limited fracture toughness (KIC) and flexural strength (σFS) are major factors limiting wider scale application as structural implant materials. KIC and σFS of ceramics can be improved through grain size refinement and through the addition of various reinforcement materials. The bioceramic hydroxyapatite (HA), the primary inorganic component of bone, has excellent osteoconductivity which offers ...
