The characteristics of pulsing patterns in the SPS process were investigated, and the effect of pulsing on the reactivity between Si and Mo was determined. Pulsing patterns were composed of consecutive 3 ms peaks separated by a period of no current. The peaks (voltage) increased in magnitude with an...
