Tetragonal-tungsten-bronze-type Ba,Li,Ti,Nb,O,, ceramics were synthesized and sintered under different atmospheres. The dielectric properties of such materials were determined via impedance-spectroscopy measurements. Based on an equivalent circuit, the dielectric relaxation was described. The tempe
