Abstract

The influence of silicon dioxide on the structure and dielectric properties of ceramic barium titanate was studied. The obtained results showed that Si at concentrations up to 1 mol % enters the BaTiO₃ lattice to form a BaTi_1 – xSi_xO₃ solid solution. The doping of barium titanate with silicon leads to a decrease in the size of the unit cell, a decrease in the temperature of the ferroelectric phase transition and its slight diffuseness, and the appearance of signs of a relaxor ferroelectric.
