Abstract
The main promising area of application of mesophase pitches is the production of carbon fibers. The most important qualitative characteristics of mesophase pitches when used in the production of carbon fibers are: the content of mesophase at the volume level, the maximum particle size of the mesophase, the interlayer distance d002 (after graphitization at +2800°C), the yield of volatile substances, the mass fraction of ash. At the Institute of Chemical and Oil and Gas Technologies of KuzSTU a sample of mesophase pitch was obtained at a laboratory facility for processing coal tar. This peck sample was examined by optical microscopy in reflected polarization light using the ASTM D 4616-95R18 method to determine the maximum size of mesospheres and the volume content of mesophase. Other most important indicators of the quality of mesophase pitch were also identified. The analysis of the obtained research results showed that the obtained sample of carboniferous mesophase pitch is suitable for use as a raw material in the production of carbon fibers.
