摘要: The present work is part of a model study aimed at upgrading the technique creating porosity within ceramic body via incorporation organic particles, used in traditional ceramics, exploring same time colloidal processing from coagulated slurries. method described by Lange et al., based on manipulation short-range repulsive (lubricating) hydration force and long-range attractive van der Waals force, was to pack high density bimodal mixture submicron particles (matrix) larger (inclusions) during consolidation pressure filtration dispersed suspensions added electrolyte. results reported show how rheological behaviour slurries changes through coagulation electrolyte, role played they affect state, bearing conceptual relation between interparticle potential observed behaviour.
