Hydrothermal Synthesis of Aligned Hydroxyapatite Nanorods With Ultra-High Crystallinity

Synthesized through a hydrothermal approach. in this experiment, a new composition ofcetyltrimethylammonium bromide ((chjcch2)lsn+(ch3)3br-) was designated as ctap)/ca(n03h/(nh4hhpoinaoh and distilled water under hydrothermal condition, to synthesize single crystalhap nanorods with diameter of 20 ± 10 nm and length of 80 ± 20 nm, was introduced. crystal phaseswere determined by x-ray diffraction (xrd). scanning electron microscope (sem) was applied toinvestigate the morphology. the microstructure of the hap products were further observed bytransmission electron microscope (tem) and high resolution transmission electron microscope(hrtem) with energy-dispersive x-ray spectroscopy (edx). the purity and chemical compositionof the as-synthesized powder was analyzed by ftir and inductively coupled plasma atomic emissionspectroscopy (lcp
