FIELD: electrical engineering.
SUBSTANCE: effect is provided by a selected composition of platinum resistive paste, which contains from 60 to 75 wt.% powder of platinum-clad aluminum oxide, from 8 to 22 wt.% alumina and from 16 to 18 wt.% organic binder. A study of the long-term stability of a film resistive gas sensor microheater made from the paste described above showed a current loss of less than 1.5% during continuous operation at a temperature of 450°C for 2 years.
EFFECT: increasing surface resistance of film resistors up to 2-10 ohms/square and reducing the temperature of burning the paste down to 850-900°C on alumina ceramic.
