Abstract

A method for the production of polygranular graphite bodies including the step of provisioning a mixture including a high-temperature treated anthracite having a high vitrinite content and a petroleum-based needle coke and/or a pitch-based needle coke, and provisioning at least one binder coke precursor. The method also includes the steps of forming a green body from the mixture from the provisioning step, and carbonizing and graphitizing the green body.
