Abstract
A resin bonded graphite material which is especially suitable for use as an electric contact, and a method for the production of this resin bonded graphite material. According to the invention, the resin-bonded graphite material if formed from a mixture of carbon black containing electro-graphite with a unburned graphite content of Rwherein R≧30 percent by weight, electro-graphite free of carbon black as well as binding agents. The material has a specific electrical resistance Wwherein W≧3500 μΩm, and use of the resin bonded graphite material as an electrical contact makes possible substantial exclusion of radio interference.
