Abstract
Mesophase pakes are a valuable raw material for the production of carbon fibers, which have unique properties and a wide range of applications. Studies have been conducted to obtain laboratory samples of mesophase pitches from coal tar with varying temperatures and duration of the synthesis stage of mesophase pitch. Anshliff briquettes were made from the obtained peck samples and examined by optical microscopy in reflected polarization light in order to determine the mesophase content and the maximum size of mesospheres according to the ASTM D 4616-95R18 method. The obtained research results have shown that the temperature and time of synthesis of mesophase pitch are one of the main factors influencing the formation of the mesophase structure of coal pitches.
Keywords
