Exploring High Temperature Rheology – Materials, Measurements and Applications

Viscosity, liquid density and other rheological properties are important when working with liquid and semi-solid samples. In the case of solid materials and powders, comprehensive material characterization requires additional material properties that are determined by powder rheology and dynamic mechanical analysis (DMA). Although all of these parameters can be easily measured at temperatures up to 600 °C, those same measurements are much more challenging for materials like glasses, metals, slags, rocks, ceramics and salts, which are processed at higher temperatures.
This webinar presents case studies of rheological measurements, DMA, powder rheology and even liquid density measurements at temperatures up to 1800 °C.  

Key Learning Objectives

  • Measure the viscosity and density of slag, metal, salt and glass melts at high temperatures
  • Predict your material’s behavior at varying conditions using the oscillation mode. This provides insight into a material’s viscoelastic properties and frequency dependent glass transition and enables characterization beyond viscometric fixed points.
  • Analyze solid-solid transition, softening and more by applying dynamic-mechanical analysis in torsion, tension, bending and compression up to 1,000 °C.
  • Characterize powder properties at elevated temperatures
