Abstract
The invention relates to synthetic carbonaceous granules having high mechanical characteristics and, more particularly, the granules produced from anthracite fines. The invention also relates to a process for the preparation of these granules. These granules are produced by agglomeration of fines to the form of pellets, superficial pre-baking of these pellets by an oxidizing gas at a temperature of between 650.degree. and 1000.degree. C. for a few minutes, followed by calcination at a high temperature and, finally, by crushing permitting the desired granulometry to be obtained. The synthetic carbonaceous granules, according to the invention, are used for all types of application and, in particular, for the manufacture of all types of carbonaceous paste, electrodes and carbonaceous blocks for the linings of furnaces or electrolysis cells.
