Abstract

PURPOSE: To improve a gas sensitivity and a dependency on concentration of the combustible gas detection element with a proper resistance value by using In2O3 as the main material in the effective components comprising In2O3 and Al2O3.
CONSTITUTION: The effective components of a combustible gas detection element comprise In2O3 and Al2O3, where Al2O3 occupies an effective component at the rate of 0.5W50wt%. The element has a proper element resistance value along with a sufficient gas sensitivity and a high dependency on gas concentration.
