The study describes CuxMn1.25-0.5xCo1.75-0.5xO4 (x = 0, 0.1, 0.3 and 0.5) spinels synthesized using EDTA gel processes in order to optimize the performance of high-quality spinel protective-conducting films deposited on steel interconnects. The powders obtained after 12 h of calcination in air at 1073 K are solely cubic spinels. Sintering these spinels for 12 h in air at 1423 K also leads to the formation...
Spinele manganowo-kobaltowe są obecnie badane jako potencjalne materiały powłok ochronno-przewodzących na powierzchnie stali ferrytycznych. Ze względu na wysokie przewodnictwo elektronowe oraz zdolność blokowania dyfuzji chromu, mogą znaleźć zastosowanie jako powłoki interkonektorów w ogniwach paliwowych typu IT-SOFC. Syntezę spineli manganowo-kobaltowych przeprowadzono metodą zol-żel, współstrącania...
