that a part of the large pulsed sintering current
flows into the specimen and affects the sintering
behavior. To clarify the influence of the internal pulsed
current that flows through the specimen during SPS,
measurement of the electrical resistance of the specimen
was conducted using Pt electrodes and the internal
pulsed current was successfully observed using a magnetic
probe during the sintering of ZnO and other
materials. Two Pt electrodes were installed on the sides
of a ZnO sample through a carbon die, and decrease of
electrical resistance was observed with the progress of
sintering. The internal current that flows through the
specimen during SPS was several hundred ampere, and
the ratio of the internal current to the total current was
found to be dependent on the material and the progress
of SPS process.抄録:In spark plasma sintering (SPS), it is supposed
