Hexaferrum - Wikipedia
Hexaferrum and epsilon iron (ε-Fe) are synonyms for the hexagonal close-packed (HCP) phase of iron that is stable only at extremely high pressure. A 1964 study at the University of Rochester mixed 99.8% pure α-iron powder with sodium chloride , and pressed a 0.5-mm diameter pellet between the flat faces of two diamond anvils.
