In the past, we have modified PAN fibers with potassium permanganate, shortened the oxidation time[ 14], enhanced the tensile strength of the carbon fibers[5], and studied the changes in the physical properties and microstructure of fibers during the process of oxidation[6]. in this article, the study is focused on the changes in the microstructure of PAN graphite fibers during the graphitizati...

Enhancements of oxygen-containing groups on the surface activated carbons (ACs) and degree graphitization in their structures allow a potential solution for development cathode materials Lithium Sulfur Batteries (LSBs). Despite two factors having been researched considerably, most applicable electrochemical performances method have not reached. Here chemical properties commercial AC terms funct...

The paper presents the characteristics of products annealing at temperatures 2400 and 3000 °C unburned carbon from coal fly ash in terms its possible use as a starting material graphitization process. An amorphous substance (organic substance) with an admixture some minerals has been found samples subjected to graphitization. However, graphite phase is dominant Studies have also shown diverse g...
