In this report, metal balls are superficially placed keeping appropriate distances with each other in order to maintain human eye visibility. Then, by applying electric current in order to create spark discharges and photographed the routes of discharges.Based upon the traces of spark discharges as photographed, the amount of electric'current that flows between balls does not necessarily depend upon the distances between the balls. It can also be observed that the spark discharges are not just happening partially but extend over the entire surface. By giving spark discharge current to the powder, we obtained the correlation between the amount of electric current and the diameters of test materials created. As an application example, the spark current was applied to the metal powder in the isostatic rubber press and the powder was sintered in 10 plus several seconds. This report also explains such data including the equipment used.
