Abstract
A pre-reacted resistor paint is disclosed, wherein a base metal powder, such as SnO.sub.2 is coated with a resinate solution, such as Co and Mn resinates and fired in a reducing atmosphere to form a pre-reacted conductive powder for subsequent mixing with a glass frit and a screening agent to blend a pre-reacted resistive paint, for subsequent screening onto a substrate and firing in an inert atmosphere to form a base metal resistor therefrom. Two mixtures of resistive paint are disclosed. The first resistive paint exhibiting a sheet resistivity in the range from 5,000 through 20,000 ohms per square; and the second resistive paint exhibiting a sheet resistivity in the range from 50,000 through 300,000 ohms per square. The first and second resistive paints may be blended to provide a base metal resistive paint exhibiting a sheet resistivity in the range from 5,000 through 300,000 ohms per square, with a TCR within .+-.200 ppm/.degree.C.
