Iron-Free Hydroxyapatite Powder from Synthetic Ca(OH)₂ and Commercialized Ca(OH)₂

Abstract:

The object of this study is to develop an easy and simple technique to fabricate iron-free hydroxyapatite (HA) powder from CaCO₃ using precipitation method. Previously, we successful to fabricate HA from Ca(OH)₂ and H₃PO₄, however, the calcining HA at 1000°C expose the green color with [Fe] is around 177ppm. In order to improve the quality of synthetic HA, CaCO₃ was used to fabricate Fe-free Ca(OH)₂ or Synthetic Ca(OH)₂ The resultant study indicates that CaCO₃ precursor helps to improve the quality of synthetic HA powder.
