摘要：

The electric properties of powders are fairly complicated. Especially the powder conductivity depends not only on pressure and grain size, but also on field strength and frequency of the measuring current, on the compression method (ortho/isostatic, slow/fast) etc.. In addition, the samples have to be prepared carefully. If, however, these conditions are considered correctly, very interesting results can be obtained. A few of these will be presented here: mixing rules, core surface separation, hysteresis, density repartition, anisotropy etc.. © 1979.
