N2 - Biocompatible β-tricalcium phosphate (β-TCP) powders have been successfully synthesized from recycled eggshells and phosphoric acid. The crystallization behavior and microstructure of the synthesized powders were dependent on the mixing ratio of eggshells and phosphoric acid, the starting condition of the eggshell and on the calcination temperature. The syntheses were achieved at about 900°C in air. Phosphoric acid-treated eggshells converted to hydroxyapatite (HA) and tricalcium phosphate (TCP). They were examined in the TEM and their chemistry determined by TEM/EDS. Ball milled β-TCP powder, having an average particle size of 0.8 μm, was sintered at 1200°C for 2 h. Fully densified β-TCP showed biocompatibility and no toxicity.
