“…On the other hand, by adding ammonia to adjust the pH to 8, Fan et al prepared phase-pure LSCF with a CA:cation ratio of only 1.5 (Fan and Liu 2009). Strontium carbonate has been observed as a secondary phase for calcination at temperatures of 500-600 °C due to the high stability of SrCO3, but phase-pure materials are obtained by increasing the calcination temperatures (Shao et al 2009). This is illustrated by the XRD diffractograms in Figure 6.…”

“…This can be important if a high surface area of the powder is desirable, for instance to provide a large surface area of a cathode material or enhance the sintering properties. (Shao et al 2009). Here, CA, EDTA or the combination of the two were used in experiments with all four cations of LSCF together and for the individual cations alone.…”

“…No entanto, alguns estudos comparativos realizados para diferentes precursores obtiveram a melhor razão molar entre ácido cítrico e metal (1/1,5) para a síntese dos pós perovsquita do tipo La 0,6 Sr 0,4 Co 0,2 Fe 0,8 O 3 -δ [17].…”

“…On the other hand, LSCF is a mixed electronic/ionic conductor (MEIC) with appreciable ionic conductivity. The exchange of oxygen ions occurs at the electrode surface with the diffusion of oxygen through the mixed conductor Shao et al, 2009). …”
