Zusammenfassung:The invention relates to a process for manufacturing electrodes and various carbonaceous products having improved characteristics, employed in manufacturing high density carbonaceous and graphite products with better physical, chemical, electrical and thermal properties, and enhanced mechanical strength. The chemical affinity of the coke-binder pitch system is increased on the basis of the utilization of some surfactants of the amino-amide kind, introduced in a controlled manner and in variable ratios (100 ppm-2% relative to pitch) depending on the acidity level of the coke and the basicity level of the pitch. The claimed process may also be used for manufacturing carbonaceous products of the cathodic blocks kind, nipples, carbonaceous material, anodes, electrographite granules, bricks for furnaces, etc. Inventia se refera la un procedeu de obtinere a electrozilor si altor produse carbunoase cu caracteristici imbunatatite, destinat obtinerii de produse carbunoase si grafitice de mare densitate, avand proprietati fizico - chimice, electrice, termice si rezistente mecanice superioare. Afinitatea chimica a sistemului cocs - smoala de liere este crescuta pe seama utilizarii unor substante tensioactive, de tip: amido-amine, introduse controlat si in proportii variabile (100 ppm ö 2% g fata de smoala), functie de nivelul de aciditate al cocsului si nivelul de bazicitate al smoalei. Procedeul poate fi utilizat si pentru obtinerea unor produse carbunoase, tip blocuri catodice, nipluri, materiale carbonice, anozi, granule electrografitice, caramizi pentru furnale etc.
