Hydroxyapatite/aluminum oxide composite bioceramic and preparation method thereof
The invention discloses a hydroxyapatite/aluminum oxide composite bioceramic and a preparation method thereof, relating to the field of biomaterials. The hydroxyapatite/aluminum oxide composite bioceramic is prepared from the following components in parts by mass: 40-60 parts of hydroxyapatite, 10-20 parts of shell powder, 15-25 parts of nano aluminum oxide, 5-12 parts of zirconium oxide, 3-8 parts of magnesium oxide, 5-10 parts of calcium hydrogen phosphate and 2-5 parts of nano zinc oxide. The preparation method comprises the following steps: (1) weighing; (2) ball milling; (3) cold-press molding; (4) high-temperature calcination; and (5) cooling. The hydroxyapatite/aluminum oxide composite bioceramic has higher biocompatibility, maintains the excellent actions of the hydroxyapatite, further enhances the mechanical properties of the bioceramic, and thus, is a very ideal skeleton substitute repair material.
