Rear-earth doped hydroxyapatite bioactive ceramic and preparation method thereof
The invention discloses rear-earth doped hydroxyapatite bioactive ceramic and a preparation method thereof and relates to the field of biological materials. The rear-earth doped hydroxyapatite bioactive ceramic is prepared from the following components in parts by mass: 40-60 parts of hydroxyapatite, 10-20 parts of cerium dioxide, 5-10 parts of tin oxide, 4-8 parts of lanthanum trichloride, 5-10 parts of nanometer titanium oxide, 5-10 parts of zirconium oxide and 2-6 parts of yttrium oxide. The preparation method of the rear-earth doped hydroxyapatite bioactive ceramic comprises the following preparation steps: (1) weighing; (2) ball milling; (3) cold-press molding; (4) high-temperature calcination; and (5) cooling. The rear-earth doped hydroxyapatite bioactive ceramic provided by the invention has good biocompatibility and high bioactivity, meanwhile has certain mechanical properties and can be used as a bone-repair biological material or a soft tissue repair material.
