Effect of oxidation temperature on the PTCR effect in the system of solid solutions (1-x)BaTiO3-x(Bi0.5K0.5)TiO3
Abstract
Solid solutions of (1–x)BaTiO<sub>3</sub>— x(Bi<sub>0.5</sub>K<sub>0.5</sub>)TiO<sub>3</sub> system were synthesized by solid-state reaction technique. Sintering of ceramic samples was carried out in a reducing atmosphere of N<sub>2</sub>/H<sub>2</sub> with subsequent oxidation in air. The influence of oxidation temperature on PTCR effect in ceramic samples of (1–x)×BaTiO<sub>3</sub>—x(Bi<sub>0.5</sub>K<sub>0.5</sub>)TiO<sub>3</sub> was investigated. The electron microscopy and energy-dispersive X-ray spectroscopy show the distribution of the main elements of ceramics in bulk and at the grain boundary. It was found that with an increase in oxidation temperature in the range of 600 —1000 ºC the values of the minimum and maximum resistance of ceramics increase. It was shown that with an increase in oxidation temperature of (1–x)BaTiO<sub>3</sub>—x(Bi<sub>0.5</sub>K<sub>0.5</sub>)TiO<sub>3</sub> potential barrier at the grain boundaries increases.
