Fired tile quality depends very strongly on the characteristics developed in th e aspressed tile. The achievement of ever-higher-quality tile microstructures and customized properties can benefit from scientific analysis, models, and insights. This lecture is an overview of materials parameters and processes influencing th e pressed green body:
materials characteristics, developing a controlled slurry with essential additives; spray drying to form controlled agglomerates (granules); the relationship of agglomerate structure to slurry dispersion and rheology; agglomerate flow and packing in the die;
agglomerate deformation and microstructure development when the tile is pressed.
General scientific models and parameters established for pressed ceramics are described
