Graphite-containing molded body and method for the production thereof

A graphite-containing molded body, comprising:

• graphite particles;
• at least one solid additive mixed with said graphite particles to form a mixture, said mixture containing one of at least one inorganic additive, a mixture of at least one inorganic additive and at least one additive, or at least 10 wt. % of an organic additive, said mixture being subsequently compressed, said at least one solid additive having a mean particle diameter of between 1 and 500 μm determined in accordance with ISO 13320.

A method for producing a molded body, which comprises the following steps of:

• a) mixing graphite particles with at least one solid additive to form a mixture containing one of at least one of an inorganic additive, a mixture of at least one inorganic additive and at least one organic additive, or at least 10 wt. % of an organic additive, wherein the at least one solid additive having a mean particle diameter determined in accordance with ISO 13320 between 1 and 500 μm;
• and
• b) compressing the mixture obtained in step a).

A method of using a graphite-containing molded body, which comprises the steps of:

• providing the graphite-containing molded body containing graphite particles, at least one solid additive mixed with the graphite particles to form a mixture, the mixture containing one of at least one inorganic additive, a mixture of at least one inorganic additive and at least one additive, or at least 10 wt. % of an organic additive, the mixture being subsequently compressed, the at least one solid additive having a mean particle diameter of between 1 and 500 μm determined in accordance with ISO 13320;
