Abstract
A number of physicochemical properties of samples are investigated. Changes in the electrical resistance of films based on the yttrium, terbium, and praseodymium oxides in an air atmosphere and upon interaction with different gaseous media (ozone, argon, methanol, ethanol) are studied. The ranges of operating temperatures and the maximum relative sensitivity coefficients of the films under investigation are determined.
