Abstract

PURPOSE: To obtain a stable and highly active detecting element material of even mixing without firing at high temperatures by letting metal oxide semiconductor materials precipitate and form and at the same time letting platinum group elements coprecipitate.
CONSTITUTION: Platinum group elements, e.g., Pd, Pt, Rh, etc. are added to metal oxide semiconductors, e.g., SnO2, ZnO and others such as V2O5, Fe2O3, etc. in order to enhance selectivity and sensitivity to gases and are allowed to coprecipitate, whereby the composite compund of metal oxides and platinum group elements is formed. Thereby, the need for firing at high temperatures as with conventional ones is eliminated, and the stable and long-life gas detecting element material may be obtained.
