Method for preparing hydroxyapatite-based composite bioceramic material through in-situ reaction
The invention belongs to the technical field of biomedical biomaterial preparation, and relates to a method for preparing a hydroxyapatite-based composite bioceramic material through an in-situ reaction. According to the method, calcium nitrate tetrahydrate (Ca(NO3)2.4H2O), diammonium hydrogen phosphate ((NH4)2HPO4), aluminum nitrate nonahydrate (Al(NO3)3.9H2O) and ammonium fluoride (NH4F) serve as raw materials, a chemical precipitation method is adopted to prepare fluorine-doped hydroxyapatite and aluminium oxide nanometer composite powder, and then hydroxyapatite-based composite bioceramic is prepared through hot-pressed sintering. The in-situ method is adopted to synthesize the hydroxyapatite and aluminium oxide nanometer composite powder, and uniform distribution of aluminum oxide in a hydroxyapatite matrix is improved; the prepared hydroxyapatite-based composite bioceramic has high biocompatibility and mechanical properties and can be used in the field of repairing or replacing bone tissue of a human body.
