NiO-MgO nano-particles were successfully prepared by the hydrothermal method with NiSO₄ and MgSO₄ as raw material.Microstructure and morphology of the product were characterized by means of scan electron microscopy,X-ray diffraction and energy dispersive X-ray spectroscopy.The results show the particle has a sphere-like apparent structure,and the diameter of the particle is in a range of 10~40 nm.Compared with the particles prepared by the hydrothermal method,the microstructure and morphology of the sample sintered at 380℃ remain unchanged.When the sample is sintered at 690℃,the crystallization degree is improved,and the particles are well dispersed.The particles exhibited a high stability when used as catalyst.
