Rheological Properties Optimization of Ceramic Compositions: Effect of Plasticizer and Water Content

The rheological properties control of ceramic compositions shaped by extrusion is of major interest for themanufacturers to ensure the final products quality and the profitability of the process. In this context, theFrench Ceramic Society (SFC) and ICAR-CM2T have initiated a research study to characterise the rheologicalbehaviour characterisations of two plastic ceramic bodies: stoneware and terracotta. … Weiterlesen …

Zero-Contamination High-Pressure Extrusion ofCeramic Bodies for Manufacturing Batteries –a Contribution to the Energy Transition

The development and manufacture of high-performance batteries for storing electric energy for stationaryand mobile applications are some of the most important preconditions for achieving the goals of theenergy transition. Herein, the authors report on a research and development project conducted in cooperationbetween the Fraunhofer-Institute for Ceramic Technologies and Systems (IKTS) and ECT-KEMA onthe manufacture of … Weiterlesen …

Measuring the Plasticity of Ceramic Bodies – Part 1

”Plasticity is like honesty. It is hard to define, but it is associated with certain properties.” Scott Blair “Formability refers to the property of a solid substance (solid as opposed to liquid) to react to external forces by changing its shape, without the cohesion of the elementary particles being lost. Especially for the process of … Weiterlesen …

Continuous Extrusion of Hard Metal Profiles

Owing to the specific rheological properties of different hard metal bodies, the continuous extrusion of profiles made from this material with screw extruders places high demands on extrusion technology. This applies not only to the extrusion itself, but also to the downstream process steps such as material dosing and preparation as well as the upstream … Weiterlesen …
