Resumo
Lanthanum beta-alumina powders were obtained by the simultaneous precipitation of
the cations La3+, Al3+, and by the explosive cyclotrimethylenetrinitramine or royal
demolition explosive (RDX). The preliminary composites obtained, which consist of
nanoreactors of powders were calcinated for breaking apart the agglomerates due to the
highly energetic impacts of the blast waves produced during annealing. The powders
calcined at 650 ºC for 4 h have high specific surface area, ~ 150 m2g-1. All processed
powders and green pellets sintered at different temperatures were analyzed by X-ray
diffraction for structural phase determination. Single phase LaAl11O18 pellets find
application as solid electrolytes in disposable electrochemical devices for monitoring
dissolved oxygen species in molten steel at very high temperatures, > 1500 ºC, during
steel production.
