Reaction equations for the formation of scale.
| January 1, 2021 | education
Iron scale is a mixture of oxides that are formed when iron is oxidized with oxygen, under the influence of high temperatures. In addition to iron oxide, other products are formed, because pure iron does not occur in nature, so sulfur, manganese, and carbon are also released from iron. In chemistry, it is customary to write the reaction equations for pure iron: 3Fe + 2О2 = Fe3O4; 2Fe + O2 = 2FeO; 4Fe + 3О2 = 2Fe2O3.
