▪ABOUT THE SEMINAR 

Thermoanalytical methods including thermogravimetry (TGA), differential scanning calorimetry (DSC), hyphenated thermal analysis (STA-MS), laser/light flash (LFA), thermomechanical analysis and dilatometry (TMA/DIL) play crucial roles in characterizing Thermal StabilityA material is thermally stable if it does not decompose under the influence of temperature. One way to determine the thermal stability of a substance is to use a TGA (thermogravimetric analyzer). thermal stability, kinetics of heterogeneous reactions, Phase TransitionsThe term phase transition (or phase change) is most commonly used to describe transitions between the solid, liquid and gaseous states.phase transitions, Thermal ConductivityThermal conductivity (λ with the unit W/(m•K)) describes the transport of energy – in the form of heat – through a body of mass as the result of a temperature gradient (see fig. 1). According to the second law of thermodynamics, heat always flows in the direction of the lower temperature.thermal conductivity, specific heat and expansion behavior of materials, aiding in the development, characterization, and quality control of products and processes. In this presentation examples of the application of these techniques for the development of storage materials based on salt systems (e.g. latent and thermochemical energy storage as well as batteries) and combination with hydrogen applications will be presented. Salt systems form a distinct group of materials alongside oxides and metals. Their extensive use as heat transfer media or chemical reactants in key industries such as metallurgy, nuclear and solar energy is due to their unique thermophysical properties coupled with their relatively low cost and availability. The combination of salts with different cations and anions greatly increases the variety of applications. Accurate determination of thermophysical properties such as DensityThe mass density is defined as the ratio between mass and volume. density, heat capacity and Thermal DiffusivityThermal diffusivity (a with the unit mm2/s) is a material-specific property for characterizing unsteady heat conduction. This value describes how quickly a material reacts to a change in temperature.thermal diffusivity is highly dependent on sample preparation and choice of crucible materials. Information on the Thermal StabilityA material is thermally stable if it does not decompose under the influence of temperature. One way to determine the thermal stability of a substance is to use a TGA (thermogravimetric analyzer). thermal stability and evaporation/Decomposition reactionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. decomposition behavior of salts is also important for the interpretation of experimental results. Some salt mixtures can form metastable phases, which may depend on the temperature program or other parameters of the experimental equipment. All these problems and possible solutions for the investigation of salt systems with TG/DTA/DSC/TMA/LFA instruments will be discussed in our seminar.

 

▪ABOUT THE PRESENTERS

Dr. Dmitry Sergeev started to work with the topic of thermal energy storage in 2013 in the frame of Humboldt fellow at the Research center Jülich in Germany. He leads several projects related to the thermodynamic description of salts, oxides and metallic systems, which are relevant for the energy sector and published 50 papers in peer-reviewed journals. In April 2023 he joined NETZSCH Analyzing and Testing as a Scientist in the Applications Laboratory in Selb, Germany where he continues to study thermophysical properties of inorganic compounds. At the same time, he currently has a lecture course “Thermophysics of Advanced Materials” at the Karlsruhe Institute of Technology.
