Resumo
Ion conducting, semiconducting and superconducting oxides have been sintered
to designed density and controlled grain size distribution by applying AC electric
fields at temperatures lower than those used in conventional sintering.
Temperature, electric field strength and frequency, electric current density
threshold, number of electric current pulses, constant or pulsed delivered electric
power, average particle size, particle size distribution, and green density are key
factors to be considered for a successful fabrication of ceramic pieces with
desired properties. Experiments have been carried out in fully and partially oxide
ion conducting zirconia solid electrolytes, doped barium cerate and barium
zirconate proton conductors, pure and doped semiconducting tin dioxide, in high-
TC bismuth-based superconducting oxides, and in planar solid oxide fuel cells.
Near to full density ceramic pellets have been produced with enhanced
properties. Noteworthy is the possibility of densifying ceramic bodies to full
density with controlled grain growth at considerably lower temperatures and in
short times than in conventional sintering.
