Department of Electronics Engineering, Banaras Hindu University, 221 005, Varanasi, India aut Effect of addition of La2O3 in the grain boundaries of a material based on BaTiO3 [Elektronische Daten] [A Biur] Results of an impedance study of capacitors of a material based on BaTiO3 with variable concentrations of La are presented. It is observed that variation in tanδ is related to variation in covalency of the added La at the grain boundaries. The tanδ is temperature dependent. The discussion brings out that added La controls the electron density at the grain boundaries.
