Abstract

The present invention relates to a method for production of graphite bodies. Carbon bodies are formed from a mixture of electric calcined coke particles calcined at a temperature between 1200 and 3000° C. and a binder where the coke particles have sulphur-and nitrogen content varying between 0 and 1.5% by weight and where the coke particles have an average sulphur content less than 0.6% by weight and a nitrogen content of less than 0.6% by weight, baking of the carbon bodies at a temperature between 700 and 1400° C. and graphitizing of the baked carbon bodies at a temperature above 2300° C.
