Paper Title:
Use of Complexing Agents in Hydroxyapatite Synthesis
  Abstract

Production of calcium phosphates from homogeneous solutions of Ca2+ and PO43- are studied in presence of complexing agents such as acetic acid, lactic acid, etilendiaminotetracetic acid (EDTA), iminodietanoic acid, and malic acid; solids are characterized with infrared spectroscopy (IR), powder x-ray diffraction, scanning electron microscopy (SEM) and electron dispersion spectra (EDS). The objective for this experiment was to find a suitable complexing agent to produce hydroxyapatite under mild reaction conditions. With the methodology described only tree phases are produced: brushite, monetite and hydroxyapatite. It is found a relationship among the ligand and the calcium phosphate phase obtained, where the complexing agent that provides the best working conditions for hydroxyapatite production is EDTA.
