Thermal Analysis and Thermal Physics


Großes Labor für Thermische Analyse und Thermophysik
© Fraunhofer IKTS
Laboratory for thermal analysis and thermal physics.

Thermal processes, especially heat treatment processes, as well as conditions and condition changes of materials depending on temperature, time and gas atmosphere are examined, simulated and optimized. On the one hand tools and base are a variety of thermoanalytic and thermophysic methods, which are utilized individually, as a complex or coupled with each other. On the other hand many years of experience and extensive knowledge in the methodical area and the area of material science as well as in thermodynamics and kinetics can be offered.


Products and services offered


  • Characterization of the thermal behavior of materials, pre-products and components in a temperature range of -150 to 2400 °C in inert or reactive gas atmospheres (oxidizing, reducing or corrosive gases like oxygen, hydrogen, carbon monoxide, ammoniac etc., doped gases or gas mixtures) after different kinds of preparation (milling, granulation, shaping, stocking under special conditions etc.)
  • Identification of thermodynamical and thermophysical properties and characteristics (phase transition-, conversion-, melting-, consolidation- and crystallization parameters [temperatures, enthalpies, phase diagrams] stability, heat capacity, thermal expansion coefficient, density, thermal diffusivity, thermal or heat conductivity, electric conductivity or resistance, wetting parameters etc.) in a temperature range of -150 to 2000 °C
  • Characterization, simulation and optimization of thermal processes, especially of debinding, outgassing and sintering processes by experiments, modeling and prediction (parameters for process analytic: temperature, time, process atmosphere, weight, geometry, furnace charge, energy, component size etc.)
  • Kinetic and thermodynamic analysis and modeling of thermal processes of debinding, outgassing and sintering (also on real component geometries), consulting, schooling and seminars about the entire subject
