Possibilities of Graphitization of Unburned Carbon from Coal Fly Ash

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 grain morphology individual samples. presence plate-shaped tube-shaped grains was found. As temperature increases (2400 °C), specific surface area decreases. total pore volume after process significantly lower than active carbons produced other carbon. Average diameter similar carbons. reflectance value matrix for sample graphitized characteristic graphite. Unburned Polish can be used
