MONTENEGRO HERNANDEZ, Alejandra; CERON, Nathalie Marcela e RODRIGUEZ PAEZ, Jorge Enrique. Use of chemical methods to synthesize SnO2 -TiO2 nanopartícles. Rev.fac.ing.univ. Antioquia [online]. 2008, n.44, pp.43-51. ISSN 0120-6230.
In this work, chemical routes were used to synthesize SnO2 -TiO2 ceramic powders: precipitation and polymeric precursor (Pechini) methods. The ceramics powders were characterized by Differential thermal and thermal gravimetric analysis (DTA/TGA), Fourier transform infrared spectroscopy (FT-IR), X Ray Diffraction (XRD) and scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The synthesized ceramic powders presented nanometric sized and high chemical purity.
