Iron is also found combined with other elements in hundreds of minerals; of greatest importance as iron ore are hematite (ferric oxide, Fe 2 O 3), magnetite (triiron tetroxide, Fe 3 O 4), limonite (hydrated ferric oxide hydroxide, FeO(OH)∙nH 2 O), and siderite (ferrous carbonate, FeCO 3). Most of this iron is found in various iron oxides, such as the minerals hematite, magnetite, and taconite. Iron is all that makes up iron. Answer 2: It may be made of a mixture of other magnetic metals however there are several reasons to believe that the core is made of predominantly iron. The (T c)'s for iron, cobalt, and nickel are 768°C, 1121°C, and 354°C respectively and are taken advantage of to make use of these elements in industry. After the hydrogen in the star's core is exhausted, the star can fuse helium to form progressively heavier elements, carbon and oxygen and so on, until iron and nickel are formed.
