Bound arc discharging plasma method, excited high-energy particles in chemical reactions by high-temperature plasma source, and combined with quenching technology to form a plasma process for preparation of metal or compounds nano-particles, can extremely well prepare the high mehing point （example： Ni, Fe, C, etc. ） or low melting point （ example ： Al, Zn, etc. ） nano-powders, is currently a very promising industrial production methods. Nano-powders of Zn were prepared with the bound arc discharging plasma method. The typical structure, particle size, morphology and heat stability of the nano-powders were investigated by XRD, TEM, TG and DTA technologies. The results show that the nano-powders of Zn are nano-sized with the particle size of 42 nm, have band morphology, heat stability. In addition, the nano-powders of Zn can be used as the material in the chemical promoter for its novel character of heat stability and high specific surface area.
