ABSTRACT:
Base metal resistive paints, resistors made therefrom and method for making the resistive paint are disclosed. The base metal resistive paints comprise 20 to 25% tantala glass frit and 75 to 80% tin oxide, ground to a particle size of ten microns or less; and well mixed with 25 to 35% screening agent for subsequent screening upon a suitable substrate, and firing in an inert atmosphere at a peak temperature of about 900.degree. C. The tantala glass frit preferably comprises 5 to 25% tantatum oxide. The tin oxide is preferably preheated at 450.degree. to 600.degree. C. in the presence of a reducing gas, prior to mixing with the tantala glass frit. The screening agent preferably forms no carbon residue when pyrolytically decomposed in an inert atmosphere during firing.
