Abstract
A currentlimiting effect current saturation and even its decrease on voltage increase was found in bariumdoped indium oxide ceramics sintered at temperatures of 1473 K to 1573 K For ceramic obtained at higher temperature 1673 K current limiting was not observed The results of electrical measurements xray diffraction analysis and scanning electron microscopy suggest that the electrical conduction in the material exhibiting the currentlimiting effect was controlled by grain boundaries
