Synthesis and characterization of nano-crystalline Ce1−xGdxO2−x/2 (x=0–0.30) solid solutions

Influence of the process parameters on the spray pyrolysis technique, on the synthesis of gadolinium doped-ceria thin film

“…Above this temperature no additional mass loss was recorded indicating that cerium ammonium nitrate was completely decomposed to cerium oxide at 300 8C. This behavior is in agreement with the results reported in literature [35]. It is important to notice that cerium ammonium nitrate is found to be more suitable than cerium nitrate as a precursor because cerium nitrate has higher decomposition temperature ($400 8C) [15] than cerium ammonium nitrate.…”

Structural, morphological and electrical studies of BaCe0.8Y0.2O3-δ synthesized by solution combustion method

“…Heat of combustion (flame temperature) helps in crystallization and formation of the desired phase while the gases evolved induce porosity and limit the reaction temperature and hence the particle size and surface area. The heat of combustion and gas evolution are dependent on nature of the fuel and oxidant to fuel ratio [9,10]. Therefore, among the different fuels, glycine was used since it acts as complexing agent and provides source of C and H, which on combustion form large amount of CO 2 and H 2 O with liberation of heat.…”

“…The combustion occurs within a very short time, and extremely high temperature is achieved during combustion reaction, which can be estimated using the equations used in [9] and thermodynamic data given in Table 1. The adiabatic flame temperature is 1576°C while the actual flame temperature as recorded by pyrometer is 1055°C.…”

Effect of Fe2O3 on Sm-doped ceria system solid electrolyte for IT-SOFCs

“…The ionic conductivity of ceria-based electrolytes doped with various dopants (Sm 3+ , Gd 3+ , Y 3+ , Ca 2+ , etc) at different concentrations has been extensively investigated [13][14][15]. Sm 3+ is one of the best dopants currently available for ceria-based solid electrolytes [13,16].…”
