Abstract
Semiconductor gas sensors produced with screen-printing techniques and based on home-made tin dioxide inks are presented. The ink consists o f home-made tin dioxide powder added to a polymer solution to make it screen printable on 96% alumina substrates. The major work is performe d on the preparation and the characterization of pure undoped tin diox ide powder produced by two different synthetic pathways. Inks prepared with powders from each method are consecutively handled in an identic al way to obtain gas sensors. The sensor response towards different ga ses is measured and compared for both types of starting materials.
