The electrical conductivities of the composite wires were found to be substantially lower than that of pure copper and essentially equal to the conductivity contribution of the outer copper sheath alone.doi:10.1016/0378-4363(80)90292-2S.C. Singhal...
Validity of Wiedemann-Franz-Lorenz Law leads to the knowledge of thermal conductivity indirectly by the electrical conductivity measurements. Studies on copper-manganese alloy system carried out indicated the non-availability of Wiedemann-Franz-Lorenz Law. High specific resistance of these alloys coupled ...
Electrical Conductivity of Copper Oxide Films Showing Interference ColoursTHE measurement of the electrical resistance of films of copper oxide on copper showing interference colours of the first order has given results varying from 0.002 to 15 ohms per sq. cm. at 25掳 C. On massive copper ...

Copper slag, a by-product of copper smelting and copper refining process, is an ideal auxiliary filler in the carbon-based composite with outstanding mechanical and conductivity performance [40], [41]. Nowadays, copper slag was extensively utilized in road infrastructure construction, railroad ballast...
Copper-powder-filled-epoxy composites with 10 wt % copper powder and epoxy resin were developed. dc conductivity measurements were performed on the graded composites with an electrometer in the temperature range of 28-146°C. The dc conductivity decreased with an increase in the distance in the ...
The thermal conductivity and volume resistivity of a composition obtained by pressing copper and aluminum micro(nano)powders with subsequent sintering is estimated in terms of an integrated medium theory. Similar composite materials can find use as heatsinks for high-power transistors and diodes.关键...
