FIG. 1.

Temperature-dependent resistivity of platinum bulk and of compacted platinum powders prior (“green”) and after annealing to different temperatures. denotes the relative density. Note that for the green compact the right-hand axis is used.

FIG. 2.

Residual resistivity and slope of the resistivity vs temperature curve as a function of relative density for compacted Pt powders. Closed symbols: green compacts. Open symbols: samples annealed at various temperatures up to . Inset: the linear relation between residual resistivity (measured at ) and resistivity obtained by extrapolation of the linear part of to allows one to obtain without measuring down to low temperatures.

FIG. 3.

Bulk-normalized conductivity of ideal defect-free Pt and Ag compacts (symbols) vs relative density. The experimental data points can well be described by percolation theory (solid line). Inset: percolation model, consisting of a random mixture of conducting and nonconducting spheres, as used for interpretation of the data.
