The thermal conductivity and electric resistivity of two pure copper materials and nine commercial copper alloys were measured in the approximate range 1300-1500 K. The thermal conductivity was measured by the guarded axial-rod longitudinal-heat-flow technique. The samples were contained in thin-...
Measurements are reported for the first time of a complete set of thermal conductivity and electrical resistivity data, both transverse and longitudinal, in fields up to 12.5 T between 3 and 15 K for a polycrystalline sample of copper (residual resistivity ratio equal to 108). The transverse res...

Twitter Google Share on Facebook thermal resistance Also found in:Encyclopedia,Wikipedia. n. The resistance of a material or combination of materials to heat flow across a temperature gradient, usually measured in degrees Kelvin or Celsius per watt; the reciprocal of thermal conductance. ...
Those solutes which increase the electrical resistivity most strongly, also affect the lattice conductivity most noticeably, the decrease in lattice conductivity being correlated with the increase in residual electrical resistivity for a number of solutes. Whether the solutes affect the phonon-electron ...
A guarded-axial heat-flow technique for accurately measuring thermal conductivity, electrical resistivity, and Seebeck coefficient from 78 to 400 °K on small rod samples is described in detail. Results on a 99.999% pure polycrystalline copper specimen (ρ273.16°K/ρ4.2°K = 9.0 × 102) are ...
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...
Studies on copper-manganese alloy system carried out indicated the non-availability of Wiedemann-Franz-Lorenz Law. High specific resistance of these alloys coupled with very low thermal co-efficient of electrical resistivity suggests their use as a suitable material for standard resistances. (Mr. M....

The variations of the electrical resistivity for the 1% and 3% CeO2 samples can at least partially be attributed to these modifications of the carrier concentration. Nonetheless, the resistivity increase in the 5% CeO2 sample can unambiguously be ascribed to the presence of the CeO2 inclusions. ...
