Abstract

Dense thin-film electrolyte of La0.9Ba0.1F2.9 has been fabricated on stainless steel substrates by spin coating of a complex and sintering. The resulting layers had a thickness of 4–5 μm. The effect of sintering temperature (400, 450 and 500 °C) and time (0.5, 2 and 4 h) was studied in order to cont...
