Shape Control of Hydroxyapaptite Crystal Seed and Its Effects on the in-situ Reinforcement of Calcium Phosphate Cement

The effects of the contents of different regulators including D-sorbital, mannose, galactose, glucose, and fructors on the growth of hydroxyapaptite crystal seeds were studied, and the crystal seeds obtained were then applied to the in-situ reinforcement of calcium phosphate cement. The experimental results show that the discrepancies of the surface energy and structure of the crystal of different orientations lead to different growth rates, and this is the thermodynamic foundation of its in situ reinforcement. The compressive strength of the hardening body is up to 76.1 MPa, the diamentral tensile strength is up to 24.5 MPa.
