Title: Sintering of electrically conductive powders by directly applied current heating
Abstract: In the spark plasma sintering (SPS) process, the sample powder is conventionally packed in an electrically conductive die and punches, which are usually made of graphite. When electrically conductive metals, semiconductors and ceramics are sintered by the SPS, applied electric current is expected to flow through both of a graphite die and a powder compact during sintering. In this study, sintering of these electrically conductive powders was tried by a directly applied current sintering (a modified SPS), where an electrically insulative die was used instead of a conventional graphite die. In this modified SPS, the applied electric current is expected to flow through the powder compact entirely and sintering of a powder compact may also be possible through the Joule heating of sample powder itself. As electrical conductive powders, metallic Cu powder and semiconductive β-FeSi2 powder were sintered by the directly applied current sintering using carbon punches and an insulating quartz glass die. These powders were heated by directly applied current and their sintering behaviors were compared to those of the samples sintered by the conventional SPS (using carbon punches and a carbon die). When the metallic powder, Cu, was sintered, the densification behavior was almost the same as the case of the conventional SPS. On the other hand, in the case of FeSi2 powder, the transformation to the semiconductive β-FeSi2 phase occurred at a temperature lower than when sintered by the conventional SPS. After the transformation, the shrinkage of compact became larger and the density of a sintered body was higher as compared to those of the sample sintered by the conventional SPS. It was also found that the power consumption needed for densification in this modified SPS process was significantly lower than the conventional SPS.

Dr. Mikio Ito is an associate professor in the Center for Atomic and Molecular Technologies, Graduate School of Engineering, Osaka University, Japan. He obtained his master’s(1994) and Doctor’s degrees(1997) in Engineering from Osaka University. His research focuses on development of materials processing, mainly powder processing, for functional materials with excellent performances, such as hard magnetic materials, thermoelectric materials etc. So far, he has produced nearly 140 publications. His resent research also focuses on SPS processing, and he is trying to clarify the effects of directly applied current sintering using SPS on densification behaviors of metal and ceramic powders.
