Resumo
ZrO2:Sc2O3 powders were synthesized by the polyacrylamide and the polymeric precursor techniques.
The powder particles had the state of agglomeration analyzed by laser scattering, the structural phases
by X-ray diffraction, and the morphology by scanning electron microscopy. The polyacrylamide and the
polymeric precursor techniques produced stable transparent gels and polymeric resins, respectively.
Upon calcination the gels and the resins yielded high surface area powders, fully stabilized in the cubic
fluorite structure. The crystalline phases, grain morphology and electrical behavior of sintered pellets
using powders synthesized by both techniques were analyzed. The amount of organics in the precursors
was found to be responsible for the state of agglomeration of the particles, producing pellets with different
electrical behavior.
