<p>A device for complete compacted powder resistivity measurement during powder compacting is disclosed. The device mainly includes two pistons (10S, 10I) slidably moveable inside a compacting sleeve (1). The compacting surfaces (10C) of the pistons and the inner surface (2) of the compacting sleeve (1) each comprise four electrodes, i.e. two current electrodes (4, 14I) and two voltage measurement electrodes (4, 14U). The device is useful for measuring the resistivity of compacted powders.</p> |
