How is iron created
At least four allotropes of iron (differing atom arrangements in the solid) are known, conventionally denoted α, γ, δ, and ε. The first three forms are observed at ordinary pressures. As molten iron cools past its freezing point of 1538 °C, it crystallizes into its δ allotrope, which has a body-centered cubic (bcc) crystal structure. As it cools further to 1394 °C, it changes to its γ-iron allotrope, a face-centered cubic (f… Web20 uur geleden · The key iron ore export hub of Port Hedland reopened after the biggest cyclone to hit Western Australia in at least a decade made landfall, with a major gold mine lashed by destructive winds as ...
