Recently, utilization of kish graphite has been suggested [3-6] due to the shortage of high-quality crystalline graphite in natural re- sources, as well as because of environmental con- siderations. In addition, the potential utilization of kish graphite could reduce the pressure on waste- material management in steel-making operations.

The flakes of kish graphite have a wide range of crystallinity, from 50 to 4 in ρ 300K/ ρ 4.2K even though they have been prepared through high-temperature evaporation of iron (Table 2-1).Most of these flakes show very small values of r TL and r T, indicating a high degree of planar orientation. In kish graphite flakes formed through precipitation from molten iron, …

The kish graphite had a high crystallinity and graphitization degree. Figure 4 (b) shows the XRD pattern of the ash sample. The impurities in the ash sample were mainly composed of calcium albite, hematite, and quartz. This result is consistent with kish graphite formation theory and the mineral chemical analysis results.
