Abstract
The influence of the niobium content on the anatase-to-rutile phase tr ansition in nanopowders of Nb-Ti oxides was studied and the changes in the particle size and microstrain distribution obtained at different temperatures were analyzed. A correlation is found between the initial microstructure in the Ti1-xNbxO2 (x = 0.03, 0.2) powder and the niobi um content. The presence of Nb was found to inhibit the growth of both the anatase and the rutile phases.
