Resumo
Yttria (Y2O3) has been used in many technological applications areas as luminescence
material, high temperature and strength structural material, owing to its excellent optical and
refractory characteristics. Applying conformation techniques using Y2O3 concentrated suspensions
is adequated, if it is well controlled, so that assisting to obtain homogeneous ceramic bodies,
reproductive and with complex geometry. Studies involving superficial behavior, stability
conditions of suspensions and the behavior related to conformation give important information to
control the processes in manufacturing ceramic components. In this work is presented a rheological
study of Y2O3 aqueous suspensions, which concerns to solids and dispersant concentration and pH
of media. Preparation of Y2O3 aqueous suspensions with solids concentration of 30vol% was
possible, using 1wt% of ammonium polyacrylate (PAA) that was enough to gain the lowest
viscosity of the suspensions.
