Superior sinterability of nano-crystalline gadolinium doped ceria powders synthesized by co-precipitation method

Sinterability and electrical properties of ZnO-doped Ce0.8Y0.2O1.9 electrolytes prepared by an EDTA–citrate complexing method

“…Such high temperatures often lead to problems, such as solid reactions between the components, thermal degradation, and thermal expansion mismatch. Therefore, efforts have been exerted to reduce the operating temperature of such systems, and it has been found that doped ceria electrolytes exhibit superior ionic conductivity at lower temperature ranges (773-973 K) [4][5][6][7][8][9].…”

Comparative study for low temperature water-gas shift reaction on Pt/ceria catalysts: Role of different ceria supports

“…Many syntheses have been proposed for ceria including flame spray pyrolysis [39][40], incipient wetness impregnation [41][42], co-precipitation [43][44], sol-gel [45][46], hydrothermal [47][48] and micro-emulsion [49][50]. The recent discovery of University of Connecticut mesoporous materials (UCT-1-UCT-53) by Poyraz et.…”

Preparation and Sintering Characteristics of Ce0.8Gd0.2O1.9Powder by Ammonium Carbonate Co-precipitation

“…1,2) 그러나 GDC는 치밀화가 매우 어려워 Ce와 Gd 산화물 분말을 혼 합하여 제조하는 산화물 혼합법으로 고밀도의 GDC를 얻 으려면 고온(> 1500 o C)에서 장시간 소결해야 하므로 전극 물 질과의 동시소성이 어려워진다. 1) 따라서 저온(< 1300 o C) 에서 치밀한 전해질을 제조하기 위해 수산화 암모늄, 3) 옥 살산, 4,5) 탄산암모늄 6,7)…”
