Rare-earth-doped tricalcium phosphate bioceramic and preparation method thereof
The invention discloses a rare-earth-doped tricalcium phosphate bioceramic and a preparation method thereof, relating to the field of biological materials. The rare-earth-doped tricalcium phosphate bioceramic is prepared from the following components in parts by mass: 42-62 parts of tricalcium phosphate, 12-22 parts of praseodymium oxide, 5-10 parts of ytterbium trichloride, 3-8 parts of titanium diboride, 5-10 parts of zirconium oxide and 3-6 parts of silicon nitride. The preparation method comprises the following steps: (1) weighing; (2) ball milling; (3) cold-press molding; (4) high-temperature calcination; and (5) cooling. The rare-earth-doped tricalcium phosphate bioceramic disclosed by the invention has the advantages of favorable biocompatibility, higher bioactivity, certain anti-inflammatory and bactericidal properties and favorable mechanical properties, and can be used as a skeleton repair instead of the biological material.
