Abstract
PURPOSE: To sense halogen gas even at low concentration easily and at high reproducibility, without requiring high voltage power source, by mixing Au to a specific oxide semiconductor composition.
CONSTITUTION: Proper Au compound is mixed, by 0.01 to 35 weight parts as converted to Au, to 100 weight parts of oxide semiconductor composition of which main components are ZnO 99.9 to 70 mol % and B2O3 0.1 to 30 mol %. The compound is crushed and blended, and a caking agent is added, so that a halogen gas sensitive component in paste form may be prepared. Two metal wires 2, 3, of which one works as heater, are wound parallel around the outer circumference of a cylindrical insulation base body 1 made of alumina at a certain spacing with each other, and said composition is spread, dried, heated, and baked thereon, so that is obtained a halogen gas sensing elememt 5 on which is formed a halogen gas sensing body 4. Thus, the gas selectivity is excellent, and the response characteristic in correpondence with time is stable.
