Abstract:
The aim of this work was to study the effect of samarium oxide doping on a SrTiO3 perovskite ceramic. After analyzing the data obtained on the morphological features of the synthesized
structures, it was found that an increase in the dopant concentration led not only to a change in
the morphological features, but also in the density of the ferroelectrics. Using the X-ray diffraction
method, it was found that doping with Sm2O3
led to the formation of a multiphase system of two
cubic phases of SrTiO3 and Sm2O3
. At the same time, an increase in the concentration of Sm2O3
dopant led to a change in the crystallinity degree, as well as deformation of the structure. Evaluation
of the efficiency of use of synthesized ferroelectrics as catalysts for purification of aqueous media
from manganese showed that an increase in the concentration of Sm2O3 dopant led to an increase in
purification efficiency by 50–70%.
