英文摘要: The La1−xBaxCrO3 (x = 0–0.2) negative temperature coefficient (NTC) ceramics have been prepared by the traditional solid-state reaction method at 1600 °C. Scanning electron microscope images show that the doping of Ba2+ contributes to the increase in the density. X-ray diffraction analysis has revealed that the sintered ceramics crystallize in a single perovskite structure. X-ray photoelectron spectroscopy analysis confirm the existence of Cr3+ and Cr6+ ions on lattice sites, which result in hopping conduction. The presence of the Cr3+ and Cr6+ ions is one of the significant factors that affect the electrical conductivity of La1−xBaxCrO3 ceramics. The resistance of NTC...
