Commissioning of the FRS 1800 high-temperature rheometer at the ITM

The FRS 1800, which is unique in Germany, enables precise rheological tests on high-performance materials up to 1800 °C. It combines a high-resolution, air-bearing rheometer head with a specially developed laboratory furnace for measuring the viscosity of melts - e.g. glasses, ceramics or metals that are processed at temperatures above 1000 °C. The FRS 1800 can be used to reliably determine key material properties such as melt viscosity or the complex shear modulus. This not only strengthens the quality of research at the ITM, but also opens up new possibilities in the development of temperature-resistant materials.

Thanks to modern functions such as normal force control, oscillation mode and the possibility of measurements in an inert gas atmosphere, thermal and mechanical properties can be analyzed under realistic conditions. The system meets international industry standards such as ASTM C965 and ISO 7884-2.

This project is co-funded by the European Union and co-financed from tax revenues on the basis of the budget adopted by the Saxon State Parliament.
