    Adjusting Properties of Electrode Pitch with Fractions of Coal Tar
    (Ukrainian State University of Science and Technologies, Dnipro, 2025) Starovoyt, Anatoly; Malyi, E.; Sorokin, E.; Starovoyt, Maria; Popova, O.
    ENG: The paper presents the investigation results of the organic mass modification of the impregnating pitch of coal tar with low pyrolysis degree. The processes that form the pitch operational properties in the impregnation technology of graphitized electrodes were studied. Specific features of the modifying additive effect on the quality characteristics of the pitch and its group composition were established. Such technological approach makes it possible to intensify the impregnation process of blanks for graphitized electrodes.

    Modification of the Electrode Pitch Operational Properties
    (Lviv Polytechnic National University, Lviv, Ukraine, 2021) Starovoyt, Anatoly; Malyi, Evgeniy; Chemerinskii, Michael; Timoshenko, Anatoly
    ENG: In this work, the influence of the carbon modifier type and its amount on the processes of carbonization of the electrode pitch and carbon masses for carbon production was investigated experimentally. The paper presents the processes that occur during the carbonization of the electrode pitch and the change in its properties during the modification process. It is shown that the most promising additive is a medium-boiling polymer mixture, which contributes to the carbonization of pitch and improves the physico-chemical properties.
