Abstract: Lanthanum hydroxide nanorods with a diameter of 10-20 nm and length up to 100-200 nm were synthesized through a direct reaction of La(NO3)3 and KOH under hydrothermal microemulsion conditions.X-ray diffraction(XRD) and scanning electron microscope(SEM) were employed for the characterization of the structure,compositions and morphology of the obtained products.The results showed that the molar ratio of water to the surfactant CTAB,concentration of La(NO3)3,reactant temperature and reactant time all could affect the morphology and size of the lanthanum hydroxide nanorods.

Key words: Rare earth, Nanorods, Hydrothermal microemulsion, Lanthanum hydroxide
