| Popis: | HA whiskers with high crystalline, uniform morphology and high aspect ratio have been successfully synthesized by the reflux-hydrothermal combined method with the aid of urea, citric acid and Na 2 EDTA additives. The effects of additives on the whiskers have been investigated in detail. The shape and composition of obtained products were characterized by XRD, FTIR, SEM, TEM and ICP-AES. It is revealed that larger aspect ratios, more uniform morphology, more pure phase composition (Ca/P), shorter reaction time and more mild reaction conditions were reached in contrast to sole reflux or hydrothermal treatment. Urea has the most remarkable effect on the aspect ratio and phase purity of HA whiskers. |
