A series of polycrystalline Sn1-xNaxSe with x = 0.00, 0.02, 0.04, 0.10 were fabricated using hydrothermal synthesis, followed by evacuated-and-encapsulated sintering. Their thermoelectric properties were then evaluated. The thermal constant analyser was used to find the thermal conductivity of each system by using the transient plane source (TPS) technique. The thermal conductivity was then used in determining the thermoelectric figure-of-merit, the ZT value of the system....
This article presented the high temperature properties of high-entropy alloys (HEAs) that will potentially be used as thermoelectric (TE) generator materials. The high temperature thermal conductivity was analyzed using the transient plane source (TPS) method through the use of a Thermal Constant Analyser. From the experimental results, it was concluded that HEAs may be used as high-performance bulk TE materials at high temperatures due to their potential to reach low ...
In this article, the thermal and tribological properties of Phenolic/Carbon Nanotube (CNT)-Alumina Hybrid composites were examined. One of the main properties that was measured was the thermal conductivity, which was measured using the transient plane source (TPS) method with the use of a Thermal Constant Analyzer. The experiment compared the thermal conductivities of the hybrid composite, mixed phenolic composite, and pure phenolic to determine which one had the ...
This article examined the thermoelectric properties of Ca3CO4O9 ceramic samples that were sintered using the hybrid microwave (HMW) technique. This microwave process was found to promote densification and grain texturing in the ceramics which increased their electrical conductivity. However, the thermal conductivity was unaffected by the microstructural changes....
This article aimed to compare the effects of casting processes and heat treatments on the thermal conductivities of the Al-10 wt% Si-0.6 wt% Cu-0.9 wt% Fe-0.7 wt% Zn aluminum alloy by using the gravity-casting and die-casting processes. The thermal conductivities were measured using an thermal analyzer which operates using the transient plane source (TPS) technique. From the TPS technique, it was observed that that the gravity-cast materials achieved a higher ...
