    Researchers from the National Institute of Materials Science at the National Academy of Sciences of Ukraine (UNMA MPI) and the Lithuanian Energy Institute (LEI) have been working to create a high-temperature ceramic material as a reference material for calibration of thermal conductivity measurement devices when the conductivity varies from 0.3 to 1.0 (W/mK). High porosity of high-temperature materials has a significant influence on the thermal conductivity. In the selection of materials, the stability of the physical-mechanical properties of the high-temperature material over a wide temperature range is important for the production of reference samples. To obtain a reliable reference material, UNMA MPI and LEI scientists used different methods to measure the thermal conductivity of selected materials: UNMA MPI applied an inverse heat conduction task method while LEI applied a standard hot wire method. The selected temperature range was from 20oC up to 1000oC.

    LEI activities in the Project

    During the project, LEI scientists investigated selected thermo-insulating material and determined how the microstructure, dimensions, compression strength and density of the sample change by heating it at a high temperature of 1000°C and the influence of thermal loads on chracteristics of reference material. A wide range of temperatures (20°C to 1000°C) was selected for the research. The thermal conductivity that is one of the most important characteristics was determined by two experimental methods: the hot wire cross and parallel method according to standard EN 993-14 and EN 993-15, respectively.
