摘要:In this study, porous HAP spherical particles were prepared by homogeneous precipitation using biological calcium carbonate as raw material, EDTANa2 as template and urea as precipitant. The effects of preparation conditions and additives concentration on phase composition, particle size and morphology were studied. SEM shows that the particle size and morphology change with reaction temperature, stirring time, precipitation time, urea and EDTANa2 concentration. XRD analysis indicated that phase composition of samples is a single phase of hydroxyapatite. The {0001}, {101¯0}, {101¯1} planes of crystal are exposed. The preparation conditions and additives concentration did not affect the phase composition. Spherical articles had high ion exchange/adsorption capacity to Cu2+ and F-.
