Abstract
A gas-sensitive composite material comprises a porous dielectric having micropores and a thin film consisting of ultrafine metal particles dispersed in, and supported by, at least the porous surface layers of the dielectric. The gas-sensitive composite material is produced by a method comprising the steps of: forming a thin film of conductive ultrafine metal particles on at least the porous surface layers of a porous dielectric and dispersing the thin film metal, in a size similar to the pore opening, continuously or partly discontinuously in the porous layers, whereby a three-dimensional composite material is obtained.
