Abstract Scope |
The design and creation of ceramic slurries and slips is often considered a balanced art of powder content, dispersants, and binders (known as backbone polymers) within an often-aqueous suspension. It has been well established that particle size has a specific influence on the flow properties of a slip, however the physical properties of a particle’s morphology play an equally important role. The aim of this research was to assess α-Al2O3 powders for their physical descriptors via particle shape and SEM analysis to highlight the physical differences between the tested powders. The powders were combined with different backbone polymers and subjected to varying shear rates and temperatures, prior to conducting comparable tests on complete slips with the same backbone polymers. The results were analysed to investigate trends and factors to assess the best processing route for the materials functionality within slip casting to ensure the creation components with excellent thermo-mechanical properties. |
