摘 要：<正>Relaxor-type ferroelectric perovskites attract a lot of attentions due to their excellent dielectric and electrostrictive properties. （Ba,La）（Mg, Nb）O3（BLMN） ceramics were synthesized from oxides by sintering in airs using a conventional mixed oxide process. Thermogravimetry-differential analyzer （TG-DTA） analysis shows that the fired temperature of the Ba（Mg1/3, Nb2/3）O3 is above 1627.2 K. From the study of X-ray diffraction （XRD） patterns, it is founded that the amount of the perovskite phase increases with the increasing amount of La2O3. Furthermore, by the X-ray photoelectron spectroscopy （XPS） analysis, it is discovered that the amount of Nb4+ is increased as La2O3 dopant increases from 0 to 0.04.
