Abstract :
The paper presents the mechanism of hollow Fe micro-sphere production in Ar plasma jet. The required condition for cavity (pore) formation and the dependence of the pore radius on the plasma jet velocity are derived. Technological data concerning the micro-sphere production are given and comparison between the model predictions and experiment is made.
