The electrical conductivity of pure aluminum oxynitride spinel was measured at 1300° to 1500°C under flowing nitrogen gas. The re sults for two nonstoichiometric spinel compositions can be fitted by exponential expressions with an activation energy of 116± I Wlmol. The mobilities calculated ...
The electrical conductivity of nominally pure and Fe-doped MgAl2O4 spinel was measured at 700 to 2000 K. The results for pure stoichiometric spinel can be fitted by exponential expressions with different activation-energy parameters in three ranges of temperature. The conductivity of a sample contain...

The thermal conductivity of three specimens of aluminum differing widely in residual resistivity was measured in the normal and superconducting states. The experimental method yielded quite accurate results of the ratio of the superconducting state thermal conductivity to that in the normal state, κκ....
The electrical conductivity of polycrystalline and single crystal AI2O3 has been determined between 1000 and 1650°C. Measuring the conductivity between the outside and inside surface of a thin-walled, hollow tube eliminates the adverse effects of gas or

Nanofluids are colloidal suspensions constituted of nanoparticles and typical heat transfer fluids which have shown potential in yielding enhanced heat tra
In this study, the enhancement in thermal conductivity of the nanofluid was similar to that of pure base fluid, i.e., water. The pronounced effect of nanoparticle concentration was seen after a certain concentration. This proves that nanofluid thermal conductivity is not always highly affected ...
This chapter reviews the thermal conductivity of nonmetallic crystals at temperatures comparable to or higher than the Debye temperature. It deals with the intrinsic behavior of such pure crystals at high temperatures. In such crystals, the dominant carriers of thermal energy are phonons and the domin...
