  • Iron(II III) oxide

    Fe 3 O 4 is used as a black pigment and is known as C.I pigment black 11 (C.I. No.77499) or Mars Black. Fe 3 O 4 is used as a catalyst in the Haber process and in the watergas shift reaction. The latter uses an HTS (high temperature shift catalyst) of iron oxide stabilised by chromium oxide.

  • How is Iron Made Into Steel? Sciencing

    Iron was the dominant metal for use in building and machinery until the modern era. Iron is still the main component of steel but when impurities are removed in the steelmaking process a stronger lighter material results (steel). Steel is used in almost all modern buildings automobiles aircraft and appliances.
