Abstract

The invention relates to a process for producing a material based on silver-carbon, that involves the steps of: (i) providing a suspension of carbon particles; and (ii) supplying a solution of a silver compound and of a reducing agent, such that a silver-containing precipitate is deposited onto the carbon particles, where the carbon particles have a mean diameter of 200 nm or greater. The invention further relates to a material obtainable by this process and to the use of the material in circuit breakers for low-voltage power engineering.
