摘 要：Hydroxyapatite whiskers were prepared by the homogeneous precipitation method. Soluble calcium ion and phosphate ion were used as initial materials, they were refluxed respectively at 85℃ , 90℃ and 95℃ for various lengths of time. A proper precipitation agent was selected to control the releasing speed of ions in the system; it induced the hydraxyapatite crystal to grow in a desired way. The pH values of each solutions were measured continuously during the reaction. After the reaction, the products were characterized by X- ray powder dif-fractometry （XRD）, scanning electron microscopy （ SEM） and infrared spectroscopy （IR）. It is shown that long hydroxyapatite whiskers were obtained under the conditions of 95℃ - 48h and 90℃ - 12h, 85℃ - 120h.
