working principle:
The powder sample placed in the solid mold receives a change in pressure so that the volume is compressed, and during the compression process, the change in resistance, resistivity, and conductivity during volume change is measured in real time after the powder sample is subjected to pressure. Until the compaction to a stable volume state, the void ratio is very close to zero.
Solve the problem that the powder sample can not be molded by the tablet or the human error caused by the measurement after the tablet is taken out.
Application note:
When the powder is compressed until it is stable, the powder void ratio is small, and the compaction density is close to the true density state, then the powder conductivity measured at this time is close to the theoretical value.
1. Describe the change trend of electrical properties of powder during compression volume change.
2. Describe the curve of the deformation or recovery process of the powder due to the cohesive force of the self-characteristics during the pressure reduction after the powder compression.
