Abstract
A palladium paste is utilized for forming a palladium film on a ceramic substrate. The paste includes a sinterable palladium powder dispersed in a vaporizable liquid vehicle. The paste also includes minor additions of titanium dioxide powder and a metal titanate powder. A preferred titanate powder is composed of strontium calcium titanate. It is found that the additions remarkably improve adhesion of the palladium film to the substrate.
