Materials of regular use in everyday life, such as glasses, ceramics, and metals, are processed or refined as melts at temperatures above 1000 °C. By determining the melt viscosity of these materials with FRS, a consistent high quality of the final product and an optimization of the energy-intensive production process can be ensured. Furthermore, these systems open up new ways in R&D of materials with a high melting point. The Furnace Rheometer Systems each combine a highly accurate air-bearing rheometer head and a lab furnace for viscosity measurements of melts at furnace temperatures up to 1800 °C (1700 °C sample temperature). There are two models available: FRS 1600 reaches sample temperatures from 300 °C up to 1500 °C. For rheological characterization of materials with a melting point above 1500 °C, FRS 1800 is the right system.
