2. Working principle
The powder sample placed in the solid mold is compressed by the pressure change. During the compression process, the changes in resistance, resistivity and conductivity of the powder sample are measured in real time during the volume change after the pressure is applied until it is compacted to a stable volume state; that is, the porosity is very small and close to zero.
Solve the human error caused by the inability to press the powder sample into tablets or taking it out for measurement after pressing.

3. Application description
When the powder is compressed until it is stable, the porosity of the powder is small and the compaction density is close to the true density state. At this time, the powder conductivity tested is close to the theoretical value.
1. Describes the trend of the change of electrical properties of the powder during the compression volume change process.
2. Describes the curve of the powder's rebound deformation or recovery process due to its own cohesive force during the pressure reduction process after compression.
3. Measurement of the resistivity of carbon composite lithium iron phosphate positive electrode materials for lithium-ion batteries.
4. Analysis and detection of conductor or semiconductor powder materials measured by the four-probe method.
