STUDY OF Bi0.5Na0.5TiO3 (BNT) SYSTEM DOPED WITH LANTHANUM (La3+) OBTAINED BY ACETIC ACID ROUTE IN SOL-GEL PROCESS

open access: yesRevista Mexicana de Ingeniería Química, 2019
This work studies the Bi0.5Na0.5TiO3 (BNT) system doped with lanthanum (La3+) at molar concentrations 0.0, 0.3, 0.6, 0.8, 1.0, 3.0 and 6.0 . The samples were synthesized by the Sol-gel method using the acetic acid route.  The bulk samples were calcined at 700 oC/1hr seeking to obtain the perovskite phase, and finally the samples were sintered at 1050 ...
