Thermal conductivity is dominantly determined by alloy composition and temperature and is scarcely influenced by fabrication condition. An addition of solute definitely decreases the thermal conductivity of Pt, and the conductivity-composition relationship is characterized by a sharp maximum at pure Pt. ...
The temperature sensor of the probe (type T thermocouple) and the heater (Pt wire) were properly calibrated. Moreover, the probe performance has been tested by means of a pure liquid (glycerin) having well known thermal conductivity by literature. Differences of about 1.5% at ambient ...
A modified 3 ω technique is designed for measurement of the thermal conductivity of polymers. In this study, samples are prepared by pressing a platinum (Pt) hot wire into melt polymers, and a LabVIEW-based virtual lock-in amplifier is employed to collect the third harmonic of the voltage ...
Thermal Conductivity of Catalyst Pellets and Other Porous Particles The thermal conductivities of catalyst pellets composed of silica, silica-alumina and nickel catalysts using these support materials have been measured by a transient method. The results are compared with the predictive models given in ...

The thermal conductivities of materials are extremely important for many practical applications, such as in understanding the thermal balance and history of the Earth, energy conversion of devices and thermal management of electronics. However, measurements of the thermal conductivity of materials under pr...
a The elastic modulus of TPS and b the maximum tensile strain of TPS versus the mass ratio of heat-absorbing microspheres under different temperatures. c The density of TPS versus the mass ratio of heat-absorbing microspheres. d The thermal conductivity of TPS versus the mass ratio of heat-ab...
The effect of filler incorporation, on the properties of cyanate ester composites, was assessed incrementally in this work. It was found that, as is the case with epoxy based encapsulants, silica filler increased cyanate ester composite thermal conductivity, Young's modulus, and dielectric constant...
摘要: The difference in thermal conductivity in the overlapping temperature range depends on the different ratio of the CuNi content of the samples. A similar sensitivity to a small difference in the composition has also been found for other Cu alloys....
