Preparation of manganese and their derivate compounds by arc plasma method

Abstract We synthesized a series of compounds by changing the plasma atmosphere. Besides manganese nanoparticles using hydrogen and helium as the plasma atmosphere, sheet-like MnC 8 and spherical Mn 6 N 2.58 are also obtained adopting liquid steam as plasma atmosphere entirely by modifying arc plasma method. The compositions, structure and morphologies of the product were determined by X-ray diffraction (XRD) and Transmission electron microscopy (TEM). Finally, we preliminarily discussed the reason of the effect of the atmosphere to the final products of arc plasma method.
