Melting point: 1811 K (1538 °C ... Iron is a chemical element; it has the symbol Fe (from Latin ferrum 'iron') and atomic number 26.
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
It is stable up to its melting point of 1,538 °C (2,800 °F). δ-Fe cannot exist above 5.2 GPa, with austenite instead transitioning directly to a molten phase at these high pressures. [ 15 ] High pressure allotropes
Melting point and standard pressure [ edit ] The following table gives the most stable crystalline structure of each element at its melting point at atmospheric pressure (H, He, N, O, F, Ne, Cl, Ar, Kr, Xe, and Rn are gases at STP; Br and Hg are liquids at STP.)
Group 8 is a group (column) of chemical elements in the periodic table.It consists of iron (Fe), ruthenium (Ru), osmium (Os) and hassium (Hs). [1] " Group 8" is the modern standard designation for this group, adopted by the IUPAC in 1990. [1]
The red lepidocrocite (γ-Fe(O)OH) occurs on the outside of rusticles, and the orange goethite (α-Fe(O)OH) occurs internally in rusticles. When Fe 2 O 3 ·H 2 O is heated, it loses its water of hydration. Further heating at 1670 K converts Fe 2 O 3 to black Fe 3 O 4 (Fe II Fe III 2 O 4), which is known as the mineral magnetite.
