Abstract: Nano-hydroxyapatite was synthesized by chemical precipitation process under the conditions below: Ca (OH) 2 and Na3PO4 were used as raw materials, an ultrasonic oscillatator was used to oscillating the system, the atomic ratio of Ca and P was controlled as 1.67, Na3P04 was dropped at appropriate rate and stirring intensity. The structure and size of target product was analyzed by SEM photos, XRD and HIR. The results show that the product, which was obtained by standing the reaction solution at room temperature for one hour after titration, was washed with anhydrous ethanol to get hydroxyapatite powder with high purity and crystallinity, and the particle size and dispersion was good. Keywords: nano-hydroxyapatite; ultrasonic chemistry; sintering Â¥Ö÷ÕâÆªÂÛÎÄҪͶÄĸöÔÓÖ¾£¿ |
