ABSTRACT
Biocompatible ${beta}$-Tricalcium Phosphate(${beta}$-TCP) powder was successfully synthesized by using a re-cycled eggshell and phosphoric acid. The crystallization behavior of the synthesized powder was dependent on the mixing ratio between the eggshell and phosphoric acid, the starting condition of the eggshell and calcination temperature. The ${beta}$-TCP was stably synthesized in the 1:1.3~1:1.5 (wt%) mixing ratios of calcined eggshell and phosphoric acid. The synthesis was achieved at about $900{circ}$ for 1h in an air atmosphere. The crystalline development and microstructure of the synthesized powder were examined by X-ray diffractometer and scanning electron microscopy.
Key words: ${\beta}$-tricalcium Phosphate, Eggshell, Synthesis, Phosphoric acid, Calcination
