Abstract

The influence of silicon dioxide on the structure and dielectric properties of ceramic barium titanate was studied. The obtained results show that Si in concentrations up to 1 mol. % enters to the BaTiO3 lattice, forming the BaTi1-xSixO3 solid solution. Doping barium titanate with silicon leads to a decrease in the size of the crystal cell, a slight diffuseness of the ferroelectric phase transition, a decrease in its temperature and the appearance of signs of a relaxer ferroelectric.
