Abstract
PURPOSE: To obtain an inflammable gas sensing element having both sufficient gas sensitivity and concentration dependence (concentration separability) by incorporating a proper quantity of calcium oxide or strontium oxide with indium oxide as the principal component.
CONSTITUTION: 70W97wt% of indium oxide (a) and 30W3wt% of calcium oxide or strontium oxide (b) are blended as effective components to obtain a sesning element. For example, In2O3, CaCO3 and SrCO3 are blended so as to give the above- mentioned composition (here, the amounts of CaCO3 and SrCO3 are calculated based on CaO and SrO, respectively), and molded into a disc-type element in which a platinum wire electrode is buried, which is then sinstered in the air for approximately 3 hours at 600W800°C, to obtain a gas sensitive material (sintered material.)
