Nitrate–citrate combustion synthesis and properties of Ce1−xCaxO2−x solid solutions

Effect of co-doping of Mg and La on conductivity of ceria

“…Ionic conductivity is closely related to formation of oxygen-vacancies and their migration [4][5][6]. Ceria (CeO 2 ) itself is not a good ionic conductor but its ionic conductivity increases significantly with introduction of oxygen vacancies by doping of aliovalent cations in ceria as given below [7]:…”

A systematic study on the synthesis of Ca, Gd codoped cerium oxide by combustion method

“…Huang et al [10] reported the hydrothermal synthesis and properties of Ce 1−x Ca x O 2−ı solid solutions, where a sintering temperature of 1400 • C was reported for achieving 95% sintered density. Recently, Peng et al [11] reported the synthesis of nanocrystalline Ce 1−x Ca x O 2−ı solid solutions by nitrate citrate combustion synthesis. Rodriguez et al [12] investigated the structural and electronic properties of Ce 1−x Ca x O 2−ı systems.…”

Preparation of nano-Cr2−xAlxO3 (x=0–1) solid solution powders by using citrate-dispersant method

“…Nano-crystalline mixed oxide solid solutions are of current interest and have been widely studied due to their novel physical properties and potential technological applications [1][2][3][4][5][6][7]. These nano-crystalline mixed oxide solid solutions have the same crystalline structure and their crystalline size, lattice parameters and lattice volume can change with an increase in the amount of substituted/dopant elements [7][8][9][10][11][12].…”
