"We have studied the effect of adhesion promoters (bismuth and copper oxides) on the gas sensing properties of screen-printed tin and tungsten oxide sensors. The gas-sensitive pastes were prepared by mixing either tin or tungsten oxide powders withan organic vehicle based on therpineol.

The films that resulted after printing and firing have highh porosity and excellent adherence. Morphology studies have shown that the films have well-defined microstructure and gas sensitivity studies have shown that additives, not only help in promoting film adhesion, but also modify the response of the sensors.
