Innovative characterization of flow behavior of ceramic suspensions using a new Linearized Rheological Model (LRM)

Popis výsledku v původním jazyce

The determination of dynamic viscosity is a crucial factor in advanced ceramic technologies, particularly in optimization of processing conditions for ceramic suspensions and in research related to cutting-edge techniques such as 3D printing, injection molding, or slip casting. Although numerous rheological models exist, many do not accurately describe the rheological behavior across the entire range of volume fractions or are only applicable to specific conditions, such as low or high ceramic content. In this study, we introduce a novel, mathematically derived linearized rheological model for characterizing ceramic suspensions. While most rheological model verifications in the literature rely on existing datasets, our proposed model is rigorously tested against six newly measured ceramic systems, spanning different temperature ranges and shear rates. These measurements enable an objective assessment of the model's functionality, eliminating the need for fitting constants and ensuring robust validation across varied conditions. Furthermore, the model can be mathematically re-expressed in the form of a classical rheological equation, wherein the relative viscosity is treated as a function of volume filling. Upon transformation, the resulting function adopts an exponential form and takes the form of a Mooney type equation.
