Estimating the term…
The present invention relates to a screen-printing paste composition for producing an electrical conductor arrangement, which screen-printing paste composition comprises particulate noble metal, comprising platinum and palladium, metal oxides, and organic binders and/or solvents, the proportion of the metal oxides in the screen-printing paste composition being 5 to 15 wt. %, based on the total amount of platinum and metal oxides. Suitable screen-printing paste compositions can be processed to form composite products by means of application to a substrate, subsequent drying and baking, which composite products can be used, for example, in particle sensors or heating devices. The particle sensors and heating devices thus produced are characterized by improved adhesion to the substrate at high temperatures and by conductivity, and demonstrated very good reproducibility of the electrical resistance in different production batches.

A screen-printing paste composition for producing an electrical conductor arrangement comprising:
A composite product comprising a ceramic substrate and an electrical conductor arrangement on at least one side of the ceramic substrate, wherein the electrical conductor arrangement is based on particulate, spherical, noble metal, comprising platinum and/or palladium, and metal oxides, and wherein the proportion of the metal oxides makes up 5 to 15 wt. % based on the weight of the electrical conductor arrangement.
