Abstract Dielectric properties of low-firing Pb(Mg1/3Nb2/3)1−x Ti x O3-Bi2O3/Li2O ceramics are studied in this work. With the addition of Bi2O3/Li2O eutectic composition, the sintering temperature of PMN1−x PT x could be lowered to 900° C. Relaxor behaviour of PMN1−x PT x is enhanced by the incorporation of Bi2O3/Li2O due to the substitution of Bi+3/Li+ into the PMN1−x PT x framework. Bi2O3/Li2O eutectic composition is used as a fluxing agent, Curie shifter and depressor. Evaporation of Bi2O3/Li2O and PbO during firing is checked and examined via energy dispersive spectrometry (EDS) and X-ray diffraction (XRD) is used to clarify the Curie shifting and depressing effect of Bi2O3/Li2O.
