Abstract
Investigations have been made on the influence of the preparation and sintering of various tin dioxide powders on the electrical properties of ceramic SnO2 gas sensors produced from these powders. The resistanc e response of these sensors has been studied on exposure to hydrogen a nd sulfur dioxide at temperatures up to 400-degrees-C. The best sensit ivity is attained for hydrogen using tin dioxide with particle sizes o f about 0.1-0.2 mum and deposition of Pd on the surface of the powder. The influence of the sintering temperature on the sensor properties, such as gas sensitivity or response time, is discussed.
