WebSep 7, 2024 · In iron foundries, the stable iron–graphite diagram is dominating. By introduction of substantial amounts of silicon (> 1 wt.% Si) into a ternary Fe–C-Si composition with silicon atoms substituting iron atoms in the lattice, graphite formation is favored instead of cementite. WebSince graphite is a crystalline solid it can be defined by a basic unit cell. Graphite is hexagonal and therefore is defined by a hexagonal unit cell. The hexagonal unit cell of graphite is a rhombic prism (not a hexagonal prism). The prism is defined by six surfaces: four sides and a top and bottom.
