摘要
Calcium oxide was successfully derived from eggshell waste. It was employed as a calcium precursor in order to prepare hydroxyapatite. It can be noted that eggshell presented high thermal stability, and it was calcined from 700 to 1000 °C for 3 h for calcium oxide formation. Morphological properties were investigated, and it presented the irregular shape with a variation on size. The feasibility of calcium oxide for hydroxyapatite preparation was evaluated by the chemical precipitation with phosphoric acid. X-ray diffraction confirmed that single phase of hydroxyapatite was obtained.
