Résumé :

TiO//2 submicronic powders have been synthesised by controlled hydrolysis of titanium tetraisopropoxide. The influence of reagents concentration has been investigated. Additions of Niobium result in spherical particles. Mixed powders of TiO//2-SnO//2 have been produced by hydrolysis of SnCl//4-SbCl//3 solutions containing the Nb doped TiO//2 particles. The SnO//2-TiO//2 solid solutions are easily formed from 1100 degree C. However, the incorporation of the specific dopants is limited. The electrical conductivity is a non-linear function of the composition.
