| Abstract Scope |
Accurate measurement of thermophysical properties—such as thermal diffusivity, thermal conductivity, thermal expansion, and simultaneous thermal analysis (STA)—is essential for the development of materials used in nuclear applications, including graphite and ceramic composites. In this work, we present the development of a suite of advanced instruments equipped with graphite (up to 2800 °C) and tungsten (up to 2400 °C) heating elements and furnaces. These systems enable high-precision thermal diffusivity measurements via Laser Flash Analysis (LFA), thermal expansion measurements using a push-rod dilatometer, and simultaneous DSC/TGA analysis at temperatures up to 2400 °C. These ultra-high-temperature instruments have been successfully employed in several critical projects to obtain thermophysical property data that are otherwise challenging to acquire. |
