This paper discusses thermal conductivity measurements on homogenous and non-homogenous materials, using three transient methods: Laser Flash Method (LFM), Modified Hot Wire (MHW), and the Transient Plane Source (TPS). This article also compares the non-destructive nature of the MHW, and the TPS methods, to the destructive nature of the LFM. Research conducted on homogenous materials produced comparable results using all three transient methods. However, when testing non-homogenous materials, such as ...
Barium titanate-based ceramics are most commonly found in electronics as dielectric layers in multilayer ceramic capacitors. Two different forms of Barium titanate-based ceramics were analyzed in this article to determine heat capacities as a function of temperature. The thermal conductivities and thermal diffusivities of these two forms were also determined using the Hot Disk Transient Plane Source method. Inferences towards the performance and reliability of barium titanate-based ceramics under various ...
