ZrO2-toughened bioactive ceramic powder material for 3D printing and preparation and application thereof
The invention belongs to the field of preparation of biomedical materials, and particularly discloses a ZrO2-toughened bioactive ceramic powder material for 3D printing and preparation and application thereof. The preparation method includes the following steps that a dispersing agent is added into a mixed solvent of deionized water and moisturizer and stirred, and the pH value is adjusted to 9-11; then, the mixed solution is added into mixed powder of biomedical powder and ZrO2 powder, and ball grinding is performed to obtain slurry; the slurry is pre-frozen and then freeze-dried, and the dried powder and a water-soluble binding agent are screened respectively; the screened powder and the screened water-soluble binding agent are subjected to ball grinding to obtain narrow-size-distribution powder, namely, the ZrO2-toughened bioactive ceramic powder material for 3D printing. The particle size of the powder prepared through the method is in a micro-nano level and is distributed within a narrow range, and under the dispersion strengthening and toughening and phase toughening effects of ZrO2 particles, the prepared product is good in biocompatibility and high in strength and toughness.
