Abstract

Hydroxyapatite (HAp) powders were prepared via reaction of orthophosphoric acid and calcium hydroxide with a molar ratio of Ca/P = 1.67. FTIR spectrum of all samples showed peaks corresponding to O-H, hydrated O-H and PO₄³⁻ . SEM photomicrographs indicate that for samples with 1 hr and 1.5 hr stirring time, as ultrasonic stirring time increases particle size decreases. Also, the addition of lithium resulted in relatively uniform particle size and polygonized powder. Presence of Hap was confirmed based on XRD patterns. Moreover, the addition of Lithium resulted to narrower peaks which indicate increase in crystallinity.
