Physical Properties of Iron. It rusts in damp air but not in the dry air. It dissolves readily in dilute acids. At room temperature this metal is in the form of ferrite or α-form. At 910 C it changes to γ-iron which is much softer in nature. It melts at 1536 C and boils at 2861 C. Being a metal is magnetic in nature.
Another important physical property of iron ore is its porosity. It facilitates access of reducing gas into the interior of the lump ore.

In the Earth iron occurs mainly in iron-oxide ores. One of these ores is lodestone or magnetite named for its property of magnetism. Hematite is the most plentiful ore but it contains less iron than magnetite. Limonite and siderite are less abundant ores of iron. Iron alloyed with nickel is also found in meteorites.See also mineral.
β-Iron: It is a form stable between 768 C and 910 C. It is alpha iron that has lost its magnetism. It does not dissolve carbon. γ-Iron: This form is stable between 910 C and 1390 C crystallizes in face-centered cubic. It is nonmagnetic and dissolves 2% carbon at 1102 C. Carbon in solution forms a hard carbide.
