In this work, bioceramic carbonated hydroxyapatite (CHA) was synthesized from abalone mussel shells (Halioitis asinina) using a co-precipitation method; CHA-based scaffolds were fabricated with honeycomb (HCB) as the porogen agent. The concentration of HCB porogen varied among 10, 20, 30, and 40 w t%. The Energy Dispersive X-Ray Spectroscopy (EDS) analysis revealed that the Ca/P molar ratio of CHA was 1.73, which was close to natural bone’s Ca/P molar ratio of 1.71. Fourier Transform Infrared Spectroscopy (FTIR) and X-Ray Diffractometer (XRD) tests revealed that the formed phase of the synthesized CHA was of the B-type. Analysis of the pores structure showed an increasing porogen concentration, pores size, and porosity of the scaffold. The addition of HCB porogen also decreased the crystallite size. This was very good for bone growth because the low crystallinity created dislocations, making it …
