Abstract

Tin dioxide based ceramics in the SnO₂-Bi₂O₃ -Co₃O₄-Nb₂O₅-Cr₂ O₃ system exhibit highly non-linear voltage-current characteristics (non-linearity coefficient reaches 55-60 in electric fields of about 3500 V cm^-1) in parallel with high humidity sensitivity in low electric fields (humidity sensitivity coefficient reaches 10⁵). Such ceramics can be used for the fabrication of a device with combined varistor and humidity sensor properties. Voltage-current characteristics of ceramics with different amounts of bismuth oxide are studied in air with different relative humidity contents.
