abstract

a synthesis of doped ceria by combustion method is performed. two types of fuel such asurea and glycine is used to investigate the effect of fuel reactivity and reaction rate on themorphology of the resulted powders. thermo gravimetric analysis is carried out by (tg/dta,rigaku thermalplus tg 8120) to study the exo–endo temperature of as-received powder. thecrystalline phases are identified by x-ray diffraction analysis (xrd). the average crystallitesize, d, is estimated by using the scherrer formula about 40nm. the calculated lattice parameteris 5.44å. a ft-ir study is carried out on the obtained gel and reveals that a glycine-metalcomplex is formed in alkaline conditions which help in preventing metal ions selectiveprecipitation and in maintaining the compositional homogeneity of the resulted powder.finally, the effect of ph value, in the primary solution, and fuel type on the powdercharacteristics such as lattice parameter and morphologies are described.

Microwave induced combustion Synthesis of Nano- Codoped Ceria and their electrical properties

In this work, Ce0.75Gd0.1Ca0.15O1.8 nanopowders are successfully synthesized by a Glycine-nitrate combustionprocess under the microwave irradiation. Then calcination was carried out at 700 °C. Calcined powdersidentified by room temperature X-ray diffraction were single phase and had a crystallite size between 16 to 24nm (based on Schererr formula). Scanning electron microscopy (SEM) was employe...
