Crystallization and Grain Growth Kinetics for Precipitation‐Based Ceramics: A Case Study on Amorphous Ceria Thin Films from Spray Pyrolysis

“…[19][20][21][22][23][24] In view of the broad field of applications for zirconia and ceria-based ceramics such as gas sensor materials, [25][26][27][28] electrolyte, and anode materials for microsolid oxide fuel cell membranes, [22,24,[29][30][31][32][33][34] oxygen pumps, and catalytic supports for automotive exhaust [35][36][37] or even biological systems [38] this is problematic. For one metal oxide material the thin film properties vary strongly depending on the ambient state of crystallization and grain growth, and original content of organics and hydroxyl-groups after preparation.…”

Poisoning of Temperature Independent Resistive Oxygen Sensors by Sulfur Dioxide

“…In the past decade resistive oxygen sensors based on titanates or other transition metal oxides were suggested by several authors for lambda control in automotive exhausts [1][2][3][4][5][6]. Recently, it has been reported on compositions with temperature independent resistance behavior (e.g.…”

Analysis of Charge Transport in Ce0.8Gd0.2-xPrxO2-δatT≤ 600°C

“…These applications range from high temperature regime applications like solid oxide fuel cell components [1, 2] and gas sensors [3] to applications at quite low temperatures like catalyst materials [4,5] and the pharmaceutical field [6,7]. Although its standard application temperature (500-800 °C) is already considerably lower than for the comparable yttria-stabilized zirconia [8], measurement data on the low temperature charge transport and especially on the low temperature behavior of the partial conductivities of doped ceria are sketchy.…”
