The thermal conductivity and electrical resistivity of indium
Philosophical Magazine, 1962Abstract Values for the thermal conductivity, electrical resistivity and Lorenz number of the metal indium are reported for the approximate temperature range -190° to 120°C. The Lorenz number no longer behaves anomalously and the value hitherto listed for the thermal conductivity of indium at normal temperatures is considered to be low by a factor of 3·

Electrical resistivity and conductivity of greases: An initial study
Lubrication Science, 2002AbstractInvestigations of railway wagons fitted with rolling‐element bearings have shown damage to the bearings from the passage of electric current. This also occurs in railway wagons without an electric energy consumption of their own, because of residual currents from electric locomotives. This phenomenon gives rise to technical, financial, and even

Electrical contact resistance for a conductive Velcro system
Tribology International, 2014Conductive Velcro fasteners are employed as a joining material for various types of connections due to their detachable properties, especially when an electrical connection is established. Due to microscopic actual contact spots between the fibers and hooks in the Velcro joints, a large electrical contact resistance is established that could cause heat

Electrical resistivity and thermal conductivity of UP1−xSx
Journal of Physics and Chemistry of Solids, 1976Abstract UP, US, and their solid solutions of several compositions were prepared, and the electrical resistivities of these samples were measured from liquid nitrogen temperature to 1000 K and the thermal diffusivities from 300 to 1000 K. It was shown that the resistivity of UP 1− x S x at the paramagnetic region arose mainly from the scattering ...

Micromechanical approach for electrical resistivity and conductivity of sandstone
Journal of Applied Geophysics, 2014Abstract The objective of this work is to employ the micromechanical approach for the modeling of the electrical resistivity and of the conductivity of sandstone. This type of rock is considered as a mixture of solid mineral and porous space filled fully or partially by conductive water.

Estimation of the volume resistivity of electrically conductive composites
Polymer Composites, 1997AbstractThe modeling of the electrical conductivity of polymer composites reinforced with conductive fibers is investigated. Existing models generally can be divided into percolation theories and non‐percolation theories. The basis of the percolation theory is the fact that the conductivity of the composite increases dramatically at a certain fiber ...

Determination of the electrical conductivity of heat-resistant concretes
Refractories, 1994The problem of the electrical conductivity of heat-resistant concretes and bonding agents is considered and a method for determining this parameter is suggested. In addition to the thermal resistivity, the electric conductivity is a factor affecting the lifetime of lining materials for high-temperature devices.

Resistance heating using electrically conductive cements
Advances in Cement Research, 2004Steel fibre (8 μm diameter, 0·72 vol.%)-reinforced cement was found to be effective for resistance heating. A DC electrical power input of 5·6 W (7·1 V, 0·79 A) resulted in a maximum temperature of 60°C (initial temperature = 19°C) and a time of 6 min to reach half the maximum temperature. Efficiency of energy conversion increased with time of heating,

Electrical properties of conductive and resistive ZnSe layers
Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 2008The authors have investigated the electrical properties for one typical set of Al-doped ZnSe layers: one is conductive (type I) and the other is resistive (type II). The two types of ZnSe:Al layers are grown on different substrates by molecular-beam epitaxy under the same conditions: type I is on a 15° tilted (001) GaAs substrate and type II is on an ...
