Preparation of manganese and their derivate compounds by arc plasma method

We synthesized a series of compounds by changing the plasma atmosphere. Besides manganese nanoparticles using hydrogen and helium as the plasma atmosphere, sheet-like MnC8 and spherical Mn6N2.58 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.
