Experimental setup

Many industrial branches like aerospace, nuclear technology and glass production operate plants at temperatures above 1500 °C. For process optimisation and increasing their competitiveness, these industries develop new kinds of materials for use at higher temperatures. The superordinate goal of the project is to develop a metrological infrastructure for the traceable measurement of thermophysical material data up to 3000 °C. The project includes the development of reference equipment, new measuring and calibration methods and reference materials.

Project Goals

  1. Development of reference equipment for measuring the thermal conductivity for temperatures between 1500 °C and 3000 °C, including a validated uncertainty budget.
  2. Development of reference equipment for measuring the specific heat capacity of between 1500 °C and 3000 °C.
  3. Development of reference equipment for measuring the emissivity of solids above 1500 °C based on radiometric and calorimetric methods.
  4. Development of validated methods to measure the mechanical layer adhesion at temperatures above 1000 °C.
  5. Transferring these methods and the metrological infrastructure into international standards and to the end user.
