摘要：

Hydroxyapatite (HAp) nanostrips were rapidly obtained during a mild microwave heating method. Applying microwave irradiation to Ca(NO3)(2)center dot 4H(2)O/CTAB/Na2HPO4 precursor solution, the HAp precipitation process was occurred directly and without common crystallographic transformations including dissolution and slow recrystallization. The cationic surfactant CTAB was used as a soft template to modify nucleation and growth process. TEM investigations showed that the fabricated nanostrips had a width and length of about 10 and 55 nm, respectively. The X-ray diffraction pattern revealed that the fabricated well-crystallized and high purity hydroxyapatite nanostrips had a pattern similar to the bone mineral. The FTIR spectrum of the synthesized HAp nanostrips confirmed the crystallization degree observed in X-ray diffraction pattern. Moreover, the effect of CTAB on fort-nation mechanism of the fabricated nanostrips was investigated. (C) 2008 Elsevier B.V. All rights reserved.
