working principle:

The powder sample placed in the solid mold is subjected to pressure changes, resulting in volume compression. During the compression process, the changes in resistance, electrical resistivity, and electrical conductivity of the powder sample are measured in real-time after being subjected to pressure, until it is compacted to a stable volume state; The porosity is very small and close to zero

Resolve the human error caused by the inability to shape powder samples into tablets or by measuring them after compression

Application Description:

When the powder is compressed until it reaches a steady state, the porosity of the powder is small, and the compacted density is close to the true density state. At this time, the tested powder conductivity is close to the theoretical value

1. Described the trend of changes in electrical properties of the powder during the compression volume change process

2. Describe the curve diagram of the rebound deformation or recovery process of the powder due to its inherent cohesive force during the pressure reduction process after compression
