Influence of energy parameters on the product of plasmodynamic synthesis of ZnO

This paper shows the possibility to synthesize directly the nanodispersed zinc oxide (ZnO) in a hyper-velocity jet of an electric discharge erosive plasma. The investigation results demonstrate how the increase in the supplied energy W(t) influences the phase composition, structure, and dispersity of the synthesized powdered ZnO. Using the X-ray diffractometry and transmission electron microscopy it is shown that the obtained product contains only hexagonal ZnO. It is experimentally established that when W(t) varies from 13.7 to 22.6 kJ, the average particle size of the resulting product increases in the range from 80 nm to 95 nm.
