Abstract
Solid solutions of SnO 2 TiO 2 systems have recently emerged as attractive materials for application in electronic devices, particularly in gas sensor and varistor applications. Although the technological application of this (Sn,Ti)O 2 system is important, very little work had been realized to optimize the synthesis methods to obtain ceramic powders with predetermined physical and chemical properties. in this work the ceramic powders were obtained by coprecipitation and polymeric precursor methods. They were characterized with X ray diffraction (XDR) and thermical analysis (DTA / TG). We investigate the sintering parameters and some aspects of mass transport in (Sn,Ti)O 2 polycrystalline ceramics.
