[ 1 ] - Structural characterization of BaZrO3 nanopowders prepared by stearic acid gel method
Pure barium zirconate nanopowders were successfully prepared in wet-chemistry synthesismethod, using barium stearate and tetra-n-butyl zirconate as Ba, Zr sources and stearic acid ascomplexing reagent. The gel was calcined at 800 and 900 °C in air. Results of thermal analysisare given, including both DTG and TG. Fourier transform infrared spectrometry (FTIR), X-raydiffraction (XRD), transmissio...
[ 2 ] - Synthesis and characterizations of CoTiO3-clay nanocomposites by sol-gel method
CoTiO3-clay nano-composites were synthesized via a conventional sol-gel method; the gel was calcinated at 500 - 800°C for 2 hours. The presence of rhombohedra phase of CoTiO3 in clay matrix was confirmed by XRD, FTIR, SEM. Cobalt titanate-clay nano-composites were prepared with 5-20%(w/w) by sol-gel method. The spectra results were investigated at 20% (w/w) concentration .The optimum condition ...
