Biography: 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.
Title of Speech: Rapid and energy-saving sintering of electrically conductive powders by directly applied current heating
Abstract: The thermoelectric β-FeSi2 sintered body was synthesized by SPS (spark plasma sintering) using graphite punches and an electrically nonconductive quartz glass die, which we call as “directly applied current sintering”. In this process, the applied current is entirely put into a powder compact. The densification behaviour during heating and thermoelectric properties of the sample were compared to those of a sample sintered by the conventional SPS using graphite punches and a graphite die. When the electrically conductive Fe-Si alloy powder was sintered by directly applied current heating, the densification of a powder compact was significantly promoted and the density of a sintered body became higher than those of the sample sintered by the conventional SPS. It was also found that the sintering process in a quartz glass die was progressed by applying lower power consumption as compared to sintering in the conventional graphite die, leading to a significantly energy-saving sintering processing. The relative density of a compound sintered in a quartz die at 1173 K for 5 min was 96.9 %, which is almost the same as 97.3 % of the sample sintered by the conventional SPS at 1208 K for 10 min. The sample sintered by this modified SPS process showed the thermal conductivity smaller than the sample prepared in the conventional SPS process because of its finer microstructure. On the other hand, the electrical resistivity and the Seebeck coefficient of this sample were slightly reduced and enhanced, respectively, resulting in the significantly lager figure of merit as compared to the conventionally sintered sample.
