Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
The transient plane source (TPS) technique has a wide range of applications because of its capability to test solids, liquids, powders, and anisotropic materials over a range of sizes. Thermal properties of thin films and coatings can also be characterized using the TPS method if the samples are placed between the sensor and a bulk background. To minimize errors with the TPS method, use identical materials on each side of ...
The focus of this research was to discover new thermally conductive ceramic/plastic composites for their use in thermal management. In this experiment, the thermal constants analyzer was used to measure the thermal conductivity of composite films containing hexagonal boron nitride particles and polyimide. Upon testing, a thermal conductivity of 7 W/mK with a 60% filler content was noted, as compared to a thermal conductivity of 5 W/mK for the plastic ...
In this article, researchers measured the thermal conductivity of molten silicon. To avoid potential sensor harm, the standard Kapton and nickel foil sensor was swapped for a molybdenum foil, an aluminum nitride plate sensor. The regular Kapton sensor was replaced because of aluminum nitrides high resistance to the corrosive properties of the silicon melt. It was concluded that the thermal conductivity of molten silicon, at natural gravitational forces, is 45.6 W/...
In this article, researchers employed the use of the TPS method to test the thermal conductivities of various liquid materials, including mercury and silicone oils of different viscosities, in short-duration microgravity environments. The data received for the lower viscosity silicone liquids displayed extreme effects of thermal convection in the microgravity, as compared to the higher viscosity silicone liquids. When mercury was exposed to the microgravity environment, the thermal conductivity was ...
