PREPARATION OF NANOMETER POWDER BY ELECTROHYDRODYNAMIC TECHNIQUE
电流体动力学技术制备纳米超微粉的研究

The Sn-Bi nanometer powder was prepared by the electrohydrodynamic technique with quartz capillary nozzle. The processing parameters have been investigated.With the increase in DC voltage and the decrease in diameter of capillary nozzle, the particulate size of the Sn-Bi nanometer powder will be reduced. Moreover, the pressure feeding into the molten alloy is also an important factor controlling particulate size.Correspondent YU Xifeng,(Department of Materials Science, Northeastern University, Shenyang 110006)
