Fabrication of Novel Biodegradable α-Tricalcium Phosphate Cement Set by Chelating Capability of Inositol Phosphate and Its Biocompatibility

Figure 8

Microstructure of fractured cement surface, fabricated from the α-TCP powders with and without IP6 surface modification at P/L = 1/0.40 [g/cm³]: (a) α-TCP0, (b) α-TCP60, (c) α-TCP120, (d) α-TCP180, (e) IP6-α-TCP0, (f) IP6-α-TCP60, (g) IP6-α-TCP120, and (h) IP6-α-TCP180. (a) and (e) provided many voids among the grains in the fracture surface. (b)–(d) and (f)–(h) showed small particles packed among the grains, and small particles increasing with milling time.
