SUMMARY:
All stages of ceramic processing must be carefully controlled, as there is always the possibility of inserting heterogeneities in the material that could make the final products unfeasible. In this sense, rheology is one of the fundamental tools in defining the appropriate processing conditions from suspensions. In the conformation by gluing tapes (tape casting) whose parts have small thicknesses and high surfaces, the control must be even stricter, especially when the dispersing medium used is aqueous, due to problems in the drying step, however, the use of water as a dispersing medium, it is interesting because it exhibits lower toxicity and cost. Thus, in this work, the objective is to deepen the study of the rheological behavior of concentrated aqueous suspensions of zinc oxides under different concentrations of solids and additives, so that they can be formed by gluing in porous molds and gluing tapes. The initial rheological study of aqueous suspensions, stabilized with 0.7 wt.% of ammonium polyacrylate showed better shapping conditions when compared with citric acid as dispersant, being therefore more suitable for the conformation of ceramic tapes.
