ABSTRACT:
The invention is directed to a thick film resistor composition for firing in a low oxygen-containing atmosphere comprising finely divided particles of (a) a semiconductive material consisting essentially of a refractory metal carbide, oxycarbide or mixtures thereof and (b) a nonreducing glass having a softening point below that of the semiconductive material dispersed in (c) organic medium and to resistor elements made therefrom.
