Inorganic Materials Aims and scope

Abstract

The electrical properties of stoichiometric and nonstoichiometric samples of barium lead titanate ferroelectric ceramics with the initial composition Ba0.95Pb0.05TiO3 have been studied by impedance spectroscopy in weak electric fields at temperatures from 295 to 620 K and frequencies from 0.3 to 103 kHz. In addition, the optical properties of the samples have been investigated in the infrared spectral region at room temperature. The measurements were made before and after vacuum quenching, which helped to produce nonequilibrium point defects: oxygen vacancies.
