Kish Graphite
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, …

Graphite
A high-quality flake graphite product that closely resembles natural flake graphite can be made from steelmaking kish. Kish is a large-volume near-molten waste skimmed from the molten iron feed to a basic oxygen furnace, and is a mix of graphite (precipitated out of the supersaturated iron), lime-rich slag, and some iron.
