Development of metal oxide nanoparticles by soft chemical method

An extensive work for the study of SnO2 samples doped with x-mol% of Sb (x = 0, 6, 10, 14 and 18) is reported. The materials were prepared by the polymeric precursor method (Pechini method), calcined for 4 h between 800 8C and 1200 8C. The Rietveld method with X-ray diffraction data (XRD) was used t...
