Particle morphology of the prepared α-TCP powders: (a) α-TCP0, (b) IP6-α-TCP0, (c) α-TCP60, (d) IP6-α-TCP60, (e) α-TCP120, (f) IP6-α-TCP120, (g) α-TCP180, and (h) IP6-α-TCP180. In (a) and (b), the α-TCP0 and IP6-α-TCP0 powders were tens of microns of grains; however, the particle size of the α-TCP powders decreased with increasing milling time ((c)–(h)). The α-TCP180 and IP6-α-TCP180 powders were composed of small particles and aggregates as indicated by arrows ((g) and (h)).
