Microwave induced combustion Synthesis of Nano- Codoped Ceria and their electrical properties
author
Abstract:
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 employed to characterize themorphology of powder. We also studied the effect of fuel to nitrate ratio on the amount of released energyand on the crystallite size and compositional homogeneity of the resulting powders. Finally electricalproperties of obtained powder were studied.

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...

This paper reports a study on nanocrystalline ceria powder prepared by high energy ball-milling and combustion synthesis methods. The combustion synthesis was carried out using ceric ammonium nitrate as oxidizer and citric acid, glycine or citric acid plus glycine as fuel. The minimum crystallite size of ceria powder is obtained by combustion synthesis of ceric ammonium nitrate and citric acid....
