The discussed materials were prepared by solid state synthesis and a one-step sintering process. The investigations are focused on dielectric aspects of the modification. The presented results reveal that the trivalent lanthanum ions incorporate twovalent barium ions, which is connected with the creation of A-site cationic vacancies as well as oxygen vacancies. Such a scenario results in significant decreasing in grain boundaries resistivity. The activation energy of grain boundaries conductivity is significantly reduced in the case of lanthanum admixture.}, type={Article}, title={Influence of Lanthanum Dopant on the Structure and Electric Properties of BaBi2Nb2O9 Ceramics}, URL={http://journals.pan.pl/Content/114523/PDF/AMM-2020-1-26-Adamczyk.pdf}, doi={10.24425/amm.2019.131116}, keywords={ferroelectric relaxor, ceramics, impedance spectroscopy}, }
