dc.description.abstract	The study of the dielectric properties of the stoichiometric Titanium doped Sr0.255La0.03Ba0.7Nb2O6 ceramics prepared according to the formula Sr0.255La0.03Ba0.7Nb2-yTiyO6-y/2 is reported. A single phase compound is observed for low Ti content (y < 0.1) in the XRD spectra, being isostructural with the SBN phase. For high Ti concentrations (y > 0.1), the XRD patterns show, besides the SBN phase reflections, several small peaks associated with an additional phase present in the ceramics. A possible liquid phase sintering is analyzed. Strongly broadened dielectric curves are obtained in dielectric measurements, where the transition temperature decreases with the Titanium content. The diffuse phase transition coefficients are calculated, corroborating that Titanium increases the diffuse character of the transition in the monophasic region.	en_US
