Abstract
PURPOSE: To obtain the gas sensing element excellent in the gas detection sensitivity and the high temperature stability, by using the silicon carbide including selected compound from specific metal compound as catalyzer to the gas sensing body made of metal oxide semiconductor.
CONSTITUTION: H2PtCl2.6H2O or PtCl2 solution is added to silicon carbide powder and mixed and then immersed under reduced pressure, catalyzer is obtained with drying and sintering. The said catalyzer is added to the metal oxide semiconductor of ZnO-Cr2O3 system and paste is made by blending the binder such as methylcellulose with mixing. This paste is coated on the surface of the cylindrical insulator 1 having the electrode 2 and gas sensing element 4 is obtained with sintering at 300W1000°C after drying. The compound constituting the catalyzer is Pt, Pd, Rh, Re or one or more types of their compound and the amount of catalyzer compound to silicon carbide is suited for 0.05W10wt%.
