PURPOSE: To provide a composition for conductive layer being employed in the production of a resistor element insusceptible to temperature variation and withstanding high temperature high moisture conditions. CONSTITUTION: SnO, SnO2 and a fine powder mixture of metal pentoxide composed of Ta2 O5 and Nb2 O5 is sintered in a nonoxidative atmosphere at 500 deg.C or above to produce Sn2-x <2+> Tay3 Nby2 Sny1 <4+> O7-x-y1 /2 (where, x=0-0.55; y3=0-2; y2=0-2; y1=0-0.5; and y1+y2+y3=2). 5-95wt.% of pyrochlore related compound corresponding to the product is admixed with 95-5wt.% of SnO2 to produce a fine powder mixture. Alternatively, the composition has molar ratio of SnO and metal pentoxide in the range of 1.4-3.0 and SnO2 is excessive stoichiometrically as compared with SnO and metal pentoxide. |
