Fig. 5.
Representative SEM images showing low and high magnification morphologies of the four apatite-based materials: (a) bone-like mineral films (BLM), (b) sintered disks from 5.6% carbonated apatite powder (CA5), (c) sintered disks from hydroxyapatite powder (HA), and (d) sintered disks from 10.5% carbonated apatite powder (CA10). These higher magnification images show that the bone-like mineral has small surface features that relate to the bone-like mineral having a 100× higher surface area than the other three apatite-based materials.
