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 ...
This article explains the theory behind the Transient Plane Source (TPS) technique. The method measures the thermal conductivity and diffusivity of materials (solids, liquids, gels, etc.), in a rapid, non-invasive and highly accurate manner. The TPS method is a great technique to be used for thermal characterization as it has a wider thermal conductivity range (0.005 – 500 W/mK) and an easy set-up. The sensor serves as both a temperature gauge and ...
The transient plane source method was used to perform thermal conductivity, thermal diffusivity, and specific heat capacity measurements. Thermal transport properties of several thermal greases were characterized using TPS and data were compared to supplier data, received by other methods, to determine accuracy of the TPS method....
