The invention relates to the technical field of biological materials, and discloses a strontium-containing biological material and a preparation method and application thereof. The chemical composition general formula of the strontium-containing biomaterial is Sr X DSi 2 O 7 Wherein X is 1 or 2 and D is selected from Zn or Zr. The bioactive silicate biomaterial containing Sr, Zn or Zr is synthesized in a non-doping mode, has a single crystal structure, has excellent mechanical property, biocompatibility and bone induction capability, can be used as an artificial joint coating, improves the bone induction capability of the existing metal implant, ensures the long-term stability of the implant, and can be prepared into a three-dimensional porous bone repair support to repair bone injury. |
