Chelating agents role on thermal characteristics and phase formation of modified cerate-zirconate via sol-gel synthesis route

Chelating agents role on thermal characteristics and phase formation of modified cerate-zirconate via sol-gel synthesis route

Powder of BaCe0.54Zr0.36Y0.1O2.95 (BCZY) was synthesized by a modified sol-gel method. Glycolic acid, citric acid, triethylenetetramine (TETA), nitriloacetic acid (NTA) and ethylenediaminetetracetic acid (EDTA) were used as chelating agents. The role of chelating agents on the phase formation and th...

Powder of BaCe0.54Zr0.36Y0.1O2.95 (BCZY) was synthesized by a modified sol-gel method. Glycolic acid, citric acid, triethylenetetramine (TETA), nitriloacetic acid (NTA) and ethylenediaminetetracetic acid (EDTA) were used as chelating agents. The role of chelating agents on the phase formation and thermal characteristics of ceramic powders has been investigated. The obtained powders were characterized by employing thermogravimetric analysis (TGA), Fourier transform Infrared (FTIR) spectroscopy and X-ray diffractometer (XRD). Thermal decomposition of the samples was about to complete at ≈ 950°C based on the TG-DTG profile. FTIR spectra detected the trace of carbonate residue in all samples and XRD pattern showed high intensity of perovskite phase formed for sample prepared with TETA. It was found that TETA is the best chelating agent with metal nitrate salts as precursors to produce a pure phase of BCZY powders at 1100 °C. ©2012 by ESG.
