Eisenbasierter

Eisenbasierter is a German adjective used to describe materials, compounds, or technologies in which iron is the principal element or a defining component. The term is descriptive rather than a formal scientific category, and it can take different inflected forms depending on the gender, number, and case of the noun it modifies (for example, eisenbasierter Werkstoff or eisenbasierte Legierung).

In metallurgy, eisenbasierte Legierungen refer to alloys in which iron forms the matrix, such as steel or cast iron. The label covers a broad range of compositions and properties, from stainless steels with chromium and nickel to high-strength alloy steels, all built around iron as the dominant element.

In inorganic chemistry and mineralogy, eisenbasierte Verbindungen describe iron-dominated compounds and minerals, including oxides, sulfides, and complex coordination compounds. Iron oxides and related minerals play central roles in geology, catalysis, environmental science, and industrial processes.

In modern materials science, the term also encompasses iron-based technologies such as iron-based superconductors—an important class of high-temperature superconductors discovered in the late 2000s—along with iron-based battery chemistries (for example LiFePO4 cathodes) and iron-containing catalysts used in various chemical transformations and industrial processes.

Historically, iron and its alloys have been foundational for construction and engineering, reinforcing the prominence of iron as a core element in technological development. The expression eisenbasierter thus functions as a versatile descriptor across disciplines to signal iron-centered materials and systems.
