摘要：

It is shown that temperature-dependent resistivity measurements of compacted and sintered powders allow for extracting independent information on sample density on the one hand and sintering-induced changes of grain-to-grain contacts on the other hand. The temperature gradient of the resistivity as a function of sample density follows (semi-) universal laws derived from percolation theory. (C) 2005 American Institute of Physics.
