Novel bioceramic composites for bone engineering

The bioceramic composites studied for the funded project included the combinations of bioinert ceramics (alumina and zirconia), bioactive ceramics (hydroxyapatite, fluoro hydroxyapatite, bioactive glasses, and titania), biodegradable ceramics (tricalcium phosphate and calcium phosphate cement), and...
