Performance evaluation of new polymer additives for technical ceramic shaping processes

This work evaluates acrylic additives as functional agents in alumina-based ceramic formulations to identify the conditions under which they can act as dispersants, binders and/or plasticizers. The methodology links formulation, shaping, drying, debinding, sintering, and final characterization to establish robust formulation–process–property relationships. Three shaping routes are investigated: freeze granulation followed by pressing, tape casting, and robocasting. Performance is assessed through suspension/paste stability and rheology, green strength and drying sensitivity, as well as debinding/sintering behaviour and the resulting microstructure. The outcomes provide formulation guidelines to improve processability and the quality of advanced ceramic parts.
